I too am having major difficulties getting my network up and running with the new Linksys Wireless-G Router WRT54G!

I have 2 computers hardwired into it. They both see the network, and are able to use the internet. (Verizon DSL -modem Westell Model 6100.)

I have a laptop (brand new) that was able to see the wireless network and can use the internet.

I have 2 desktop computers that I am trying to set up to be wireless in an upstairs bedroom, that I have installed Linksys PCI adapters in. They both can see the network, and both show they are receiving a very good wireless connection...but CAN'T get onto the internet.

This problem has been going on for a week now and I am ready to use a sledge hammer on this router! I have been on the phone with tech for days, always following their instructions and each time....my call gets disconnected! At some point, they ask me to hold on to ask one another for more information on this problem...and bang...my call gets dropped. Then I call back, wait on hold for years and finally get through again. I have called Verizon and they tell me it's not the modem, it's the router.

I have tried it all. Reading through the previous posts, I am going to double check some of the the things I have done..and perhaps I have just skipped over something obvious. But this is making me absolutely crazy, and waisting sooo much time! I have even spoken to local tech friends who tell me they aren't sure what it is?

I think it h@ssomething to do with the Dns, or ip address. I have tried the release, renew... and that hasn't worked. I have uninstalled their software and walked through my computers commands on installing the new hardware. I have gone into the router and tried to change the configurations, uninstalled Norton in case it was conflicting. Taken down firewalls, you name it...I have tried it.

I can easily say.... I'm not a techie...although I would love to be that knowledgable about all of this! I just keep reading forums, calling tech and am trying desperately to get this connected.

If anyone has any other ideas, I would really love to hear them!!!!

Thanks!!

Interesting! I have also been having several computers attached to a WRT54GS router loosing web page connectivity (port 80 only) at intermittent times (sometimes within minutes, sometime after a couple days). I reach a point where my browser can not find any web pages (both Internet Explorer and Firefox). However, e-mail, instant messaging, FTP, sql server, and every other application using a port other than 80 continues to have connectivity and works perfectly.

Originally I thought it was DNS issue, but DNS was working perfectly when running trace-routes, pinging URLs, and running the current XP connection diagnostics they all showed DNS to be functioning but that the HTTP and HTTPS (port 443) protocols to be unable to connect. I always solve the problem by rebooting the computer to regain access to the Internet.

It does seem that certain computers seem to get the problem more often while others are never effected (e.g. my Windows 2003 Server has never been affected by this problem, but the XP Home edition seems to be extra vulnerable. Not sure about the XP Professional machines, need to pay more attention to see if they are effected.)

I finally decided it was a router problem after looking through many web forums, so I switched to a Linksys BEFSX41 router, but low and behold am still having the same problem with this router too. Linksys suggested reflashing the firmware, but I seriously doubt that two different routers, each having the current official firmware have bad flashes.

I would almost swear that there is some sort of bug in the firewall or DHCP table sections of the router software, but am not totally sure. Maybe there is some little box I need to check or uncheck in the Linksys setup pages.

P.S. I have also tried replacing the Linksys routers with both a D-link router (DI-624) and an old Netgear router (MR814) and the problem of loosing Internet access (port 80) disappears.

Hi! I am having a similar problems with my router! I have WRT54G version 2.

I have been trying to get my router going for some time. My desktop detects the wireless network but would not connect to the internet. I have already changed my settings to DSL appropriately to PPPOE and still it wouldn't connect. I have power cycled it 5 times and I have also reset the router 3 times. It still doesn't work.. I have also upgraded the firmware to version 3.03.6

What am I to do. can anybody help ! Please

not sure about all the dsl questions but the linksys routers hooked up to the cable modems screw up all the time. The reason is that the very 1st computer hooked up to the cable modem should be the only one using its service (according to the provider). Anyway the way to get around this problem is to clone the MAC address of the wired or wireless computer (i forget which one). There is a setting in one of the configuration options in the linksys router that allows you to enter in the MAC address so that the CABLE MODEM thinks that it is still hooked up to that 1st computer only, meanwhile your router will be able to route the connection properly. Try the wireless laptops MAC address 1st. To get the MAC address go to START -> RUN -> Type in CMD -> Press Enter -> type in ipconfig -> Press Enter -> look for the words MAC Address -> Type this exact address into the router. Save the changes and everything should work. The cable companies want you to but extra boxes and extra connections so they try to disable the sharing of the connection through a router.

I have had so many problems with this router, it is absulutely unbelievable. It was working this morning and then suddenly it stopped. It worked with no problems for a month but it took 2 months for that to happen. Then yesterday it suddenly decided enough was enough so I spent the whole day trying to fix it and you know what did it in the end?
I moved it 1 inch to the right.
Something is not right when a router is so temperamental that it doesn't work because someone movd it slightly. Can routers get PMS or what?
Anyways so it was fixed and everything was great until this afternoon when it randomly decides it doesn't want to work anymore!
I tried the suggestion underneath and now it won't connect at all - before it was connecting for a minute and then disconnecting. I guess this didn't work for me - but how can I get it back so that it undoes what I just did?
Arghhhhhhhhhhhhhhh I am so not tehnical, this is not fun.

I looked at the computer connected directly to the router (via ethernet cable) and found that it could no longer renew the IP address either. Clearly the problem was with the router since a direct connection to the modem worked fine.

    I updated the firmware, toyed with all sorts of settings, and made no progress. I reconfigured it both manually through the router page (point a browser to 192.168.1.1) and by re-running the linksys setup software. I uninstalled the driver for the ethernet card (right click my computer->properties->hardware tab->device manager then right click the card to uninstall), as per some instructions I found on the web, but this accomplished very little. To prove that the windows box wasn't overloading the router (again some forums suggested this), I turned it off completely and used the wireless with a mac laptop. It still failed.

    Based on the information on this page and other tests, it seemed like there was clearly a software configuration error at the level of the router. On a whim, I wondered whether some sort of automatic setup type thing was interfering with my configuration. I noticed the "Secure Easy Setup" on the wireless tab of the router page, which I had previously dismissed @ssomething for people who couldn't set things up themselves. I was wrong: I reconfigured the "SES" and NO MORE FAILURES! Wierdest of all, the SES status is still "inactive"!

    What worked for me:

    -open the router page in a browser (http://192.168.1.1)
    -click the "Wireless" tab and then click the circular icon with the lock on it
    -a dialog will open asking you to start the reconfiguration on the router
    -hold down the "Cisco Systems" button (to the left of the power light) until it starts flickering white
    -go back to the dialog box and click OK

    after a long configuration, it will bring you back to the wireless page and it will look like nothing changed, but I was then able to run simultaneously P2P-ware, 128bit WEP, QoS protocol, etc.

    Hopefully other people will notice an improvement too...

THIS IS THE FIX. Clone PC mac by going in to router config through the pc and select "clone this computer's mac". Solved all connection problems. THANKS SUP33MAN

I tihnk some of us are talking about different problems here.

Mine is not a MAC cloning issue.


I have a WRT54G v6 router with the following device attached:

Desktop PC -> RJ45
XBOX360 -> RJ45
Laptop 1 -> WIFI
Laptop 2 -> WIFI


My particular problem with my WRT54G v6 with the latest firmware is that the router will lose internet connection out of no where and cloning my desktop's MAC address is not going to work b/c I'm not using cable or DSL service where they validate your device via the MAC.

The router has been working perfectly for the last 4 months and just started acting up last week.

I live in a high rise condo where my router is hooked up to the building's high speed intranet via DHCP. When I byp@ss the router and connect straight to my building's connection, it will be perfect. With the router, for a few minutes at a time, the connection will disconnect from the intranet until I release and renew the IP / or unplug and reboot my router. Then my connection will stay for a few minutes before this starts over again.

So I have to constantly release and renew my ip so that I can get a connection few minutes at a time.

This is not a wireless connection issue since my laptops still connect to the router just fine. My XBOX360 and desktop PC is connected to the router without a problem as well since all my devices can see each other on the network.

My issue is purely the DHCP connection between the building's network and my router. When I connect my PC or laptops straight to the building's DHCP intranet, they work fine. So it's not a MAC address problem here and not the intranet. The common denominator is still the router.

I can see on the net that a lot of people is having this problem, but I don't see a solution. Can anyone help out here?

If your building has its own DHCP server, then the LinkSys router's DHCP server may cause a conflict so that your computer is never getting an IP address from DHCP.

This can be confusing, because you may have a valid IP address for a long time, but once lost, may not automatically get another like you are supposed to.

When you omit the router, then the building DHCP server works like its supposed to.

LinkSys routers have a "disable DHCP" setting that is supposed to let them work as a simple access point or switch (not router), and p@ss along the automatic IP's to your computer(s). But in my experience, LinkSys has a problem with the "disable DHCP" setting--the router still screws up the DHCP function and you cannot get IPs @ssigned through it. Your only solution may be to replace it with a wireless "access point" device or switch.

The experience of mine that I referred to is as follows:

I added a LinkSys WRT54GL v1.1 wireless router to my network, cascaded with a LinkSys BEFSR41 v2 wired router. It took me several days of pulling hair to figure out that whenever the WRT54GL router was plugged into the network, even though its DHCP server was "disabled", the other DHCP server became unreliable. (Any reconfiguration of the network caused IP addresses to get lost and not be re@ssigned). My solution was to discard the wired router and use the new wireless router plus a switch.

This is how I got my Linksys Router to finally work after having the same problems described by everyone above:

This network w@ssetup on a Bellsouth DSL connection with DHCP enabled because the DSL Modem does the PPPOE itself.

I tried using WEP several times with nearly every option besides changing the bit-depth (I left it on 64-bit the whole time). Nothing worked. I finally pressed the "Reset Security Settings" button and it set the encryption back to WPA (the default). It worked immediately.

Basically, after looking at other forums and what has been posted here it appears that this router h@ssome kind of problem with WEP encryption.

I was experience the same problem as many described.

First I was able to successfully configure the router through wire using a laptop. I could surf the internet and cruise around. BUT @ssoon as I would ENABLE the Wirless Features the internet speed would crawl and sometimes not be accessible at all.

I think it turned out to be a combination of 2 things. First cloning the MAC Address as described in an above post had to be done. 2nd the SES whatever bullsh!t kept coming up. I'm new to this techonology and there's no manual to say what it is or what it does. But pretty much if you click the lock on the Wireless tab you are looking for trouble. It turns a white flicker on the router and I @ssume it begins to broadcast traffic to see if any devices respond. If you don't have an SES enabled device I don't think you can really do anything here. So I just had to turn off my router and turn it back on and I was able to get it to work.

So:
1)Clone mac address
2)Make sure SES is Inactive (if it's not restart the router.)

This was a 4 hour pain in the @ss but it's all working now. Thanks for the above poster for suggesting both the MAC address and SES. I just couldn't get the SES configuration page like he described.

hope this helps.

I just got a new HP laptop and have been having similar problems to everything listed here. Here's the scoop.

Linksys WRT54G wireless router.
4 laptops and 1 desk top using router.
Desk top and 1 laptop plugged directly into router, other 3 laptops are wireless.
2 Laptops have vista, other 3 computers have XP (didn't know if this could be an issue because the 2 laptops that have vista also have ipv4 and ipv6 while all the XP computers have just ipv4)
My laptop is the issue - all other laptops can find, access, connect to, and use the wireless. But once I connect with my laptop nobody can use web browsers at all. The moment I disconnect with my laptop and turn the router off and then on again, the web pages work. I can plug directly into the router, as long as I have no wireless networks stored, and the network works fine. At first I thought it was a problem with the ipv6 and ipv4 interaction, but I've been told they don't interfere with each other. My dad just got a new HP laptop as well with vista and ipv4 and ipv6 and his connects to the wireless just fine and doesn't mess anything up. Then I started to compare our laptops for the difference between the two that might be the reason mine craps out the whole network - He has an intel a/b/g card and i have a broadcom a/b/g card. I didn't know if this w@ssome sort of factor as well.
I have tried all sorts of things and been to numerous sites and forums and would GREATLY appreciation any help, comments, or suggestions as to what I should try.

Thanks in advance!!

I have the same problem. I tried everything what was possible and everything what you offered. Finally I tried : 1.) I pushed SES button and I wait what happend. After cca 3minutes it h@sset up something and I was again connected to the wifi: OK
2.) I cloned my Mac address in 192.168.1.1 configuration, in "Mac address clone tab"
It was OK until I connect another laptop thru wifi. Second laptop was connected to the wifi but without internet. So I disabled clone mac address and it is running good. I am really curious how long it will takesEmoticon..
I will let you know.

INTERNET IS DOWN, F***!

I am finally, maybe, soluted the problem. Always when I change clone mac adress tab in 192.... config it will set up something that my internet is runnig good. But after couple minutes internet is down and I have to change it back to disable and my internet will wake up and running good back. Im confusedEmoticon..

Can somebody tell me now where is the problem? Can the internet provider have some software to protect internet sharing via mac address?

Hi All,

Linksys makes good routers; they really sell millions of units anually. The issue is with their interface and support. They lack informative guides, setup instructions, installation CDs and technical staff likewise. Like everyone else here, I seem to have had run into the same issue of Excellent Wireless Connectivitiy but No Internet.

Configuration:
I placed the Linksys WRT54G v7.0 router in between my Beetel DSL ADSL2 Model and the desktop connected via RJ45. I had access to the Local network, but the router would just refuse to recognize the DSL line. On my wifi laptop, again, I had access to LAN, but no Internet.

The Issue:
In my case, and as I can see in most cases above too, the issue is with the IP clash. Most of the modems you guys are using (including mine) have inbuilt routers which are configured to 192.168.1.1 and they eventually clash with the same IP on the Linksys.

What I did:
Don't touch your modem as it acts as the face to the web (DHCP) and can handle PPPoE. Instead change the IP of your Wireless router to (say) 192.168.2.1 (as I did). Release/Renew IPs (you can do this by start->cmd->ipconfig/release and ipconfig/renew) or power off & on your router.

Then, I pluggedout all the ethernet cables. Simply powered on my router with nothing connected to it except its power cable. Established wireless connection to the router and pointed my browser to http://192.168.2.1 which cleanly brings up the router login.
PS: pointing my browser tohttp://192.168.1.1 [whatever your DSL router/modem IP is] should bring up your DSL router login.

Also, make sure the 'Advance Routing' is set to 'Gateway' instead of router. This is the default settings.

PS: If your ISP requires you to register your Mac [physical] address, then you WILL have to clone your Mac address by pointing your browser to http://192.168.1.1 [or whatever you have set your router IP to]

==================================================================

Settings:DSL Modem
- IP Address: 192.168.1.1
- Subnet Mask: 255.255.255.0
- DHCP Server: Enabled
- DHCP Start IP Address: 192.168.1.2
- DHCP End IP Address: 192.168.1.254

All other settings set to their default/factory values.

Hope this helps!

OK guys, i have been looking for a solution for this problem for a while and belive it or not I FIXED IT, here is how:
solution #1
You have a virus or trojan horse or somthing in one of your pc's or laptop's, in my case i found a trojan horse that redirecting my IP address to another site, i run the virus scan in safe mode then rebooted the laptop, BANG everything works. so try switching off your pc or laptop one by one until you catch the inficted one, every time you test one you should unplug the router for 30 sec then plug again and see if you can get the internet going, eventualy you will catch it.
Solution #2 (optional)
Enable the Mac cloning then try to obtain an ip address once successful try to disable it and try to obtain an ip address again.
p.s Try updating the firmware using the update option.

I have had no trouble with the wrt54g until recently. There are now 2 laptops that are using the wifi. Previously, when there was one laptop--no problem. The problem which occurs every few days is that the laptops are not able to access the internet. (The desktop connected pc can always get to the internet during this time.) The solution is to unplug the power cord for the router and to plug it back in. Then both pcs can connect to the internet. Does anyone have any idea how to fix or what the problem is?
