It sounds like the ethernet port has actually gone bad on the router. The light turns on when the device detects a phyiscal connection to another device. Your modem does not detect a connection to the router... But it does the PC. So you know the issue is with the router.

I have a linksys wireless g router that worked fine until yesterday. Now it won't connect to the internet. I have a desktop wired to the router and a laptop used wireless.

Check if you can connect to the internet when hooked directly to the modem. If your connection works fine through the modem, then your router needs to be reconfigured.

Linksys wrt54g SRX200. I can connect to my router

It appears the connection between the Linksys and the modem is not working.
Try a different LAN cable.
Check the LAN cable from the modem to the Linksys, it should be connected to the WAN/Internet port on the Linksys.

My Linksys WRT54G Will Not Work.

It seems that your cabling is wrong. This is what it should look like:
  1. Telephone outlet to cable modem (Via telephone cable)
  2. Cable modem to router (via Ethernet cable)
  3. router via Ethernet cable or wireless to computers
Does your setup look like this? Please let me know if not so we can configure it correctly.

No more internet thru router after new modem installed

Router setup
Go to the control panel and un-install the program that the Comcast cd installed. then:
Shutdown your PC. Unplug the power from the router and the cable modem.
Wait 30 sec. then plug in the power to the cable modem, wait 30 sec. then plug the power to the router. Wait till you have "Internet" light then restart your PC. The PC should pick up an IP address and you should be able to get on-line.

Did Comcast reset you wireless router settings? If so, you may need to set up your SSID and security settings.

Customizing Wireless Settings of the Router
Having default wireless settings on the Linksys router may cause conflict with other Linksys routers within your network range. Linksys suggests changing the SSID (network name) and the Wireless Channel of your router. Also, if it is possible, enable the Wireless Security of your router.
To change the router’s SSID or the wireless network’s name, click here.
To change the router’s channel, click here.
To enable the wireless security on the router, click here.
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Linksys WRT54G wireless router not compatible with Aztech modem?

Darvin, gotta love your ISP. Never fear......

if it isn't too much of a problem (knowing you have wireless setup done already), then do a factory reset on your router ** remember to copy the WEP Key if you have, or recall the PASS PHRASE so you won't have to reset all wireless devices ** Reset is located on back, you need a ball point pen to reach the reset switch.

Reset process: unplug, take ballpoint pen & insert into reset switch & plug unit back in. Sometimes tricky, but you should notice green light goes to yellow/orange upon resetting.

RESET or NOT - you want the Linksys set for ::

Connection Type - AUTOMATIC (for automatic discovery)
Router IP Address -

DCHP - ON, Addresses - and allow 5-50 users
(for security, assign the number of DESKTOP + WIRELESS expected users +1, this way you don't get overrun without knowlege)

Take the cable from Aztech ETHERNET OUT to WAN on Linksys. (usually BLUE) (??) not 100% sure as I have the little silver pocket edition of the same Router. - power cycle (turn both DSL modem & Linksys off for 20 seconds. turn on DSL Modem, wait till it's about as ready as possible, turn on Linksys, should only take 20-30 seconds to power up & recognize.

VERIFY SETTINGS: access router -, goto STATUS. you should see IP Addressing, SubNet, DNS1 & DNS2 settings. If you do not, then you have no internet connection.


Setup Linksys Router with COnnection Type: PPoE, you will need your ISP assigned ID & Password. Follow all other instructions properly.

If you still have problems, please contact me at 906-495-1707 or via Yahoo IM or through this website.

Why does this keep happening??? Please advise...

Your modem is set to only allow one main IP address, which it assigned to your laptop.

Connect the cables through the router, then unplug first the modem, then the router.

Wait 45 seconds, then plug in router, wait 5 seconds, then plug in modem.

Give it a few seconds to talk to everything, and you should be good to go.

Connection drop-outs

Is your laptop wireless adapter a compatable brand. It doesn't necessarily mean the router is bad, you may even be getting RADIO interference from a cordlees or a cell phone in it's path. Do you have the capability to plug a cat-5 cable directly into your laptop from the router when you lose wireless? Check the wireless channels and see about changing the channel on your cordless phone too. May not work, just a hunch.

Good Luck
