I am unable to connect to the internet through my belkin wireless router.

We recently switched from ATT to Comcast in our house so we needed a new router since 2wire won't work with the Comcast modem. So we installed the router - no problems. Its been working great for about 3 weeks now, but yesterday when I tried to get on, it said the router had "no internet access" and I haven't been able to get it to work since.

I have restarted the router, the modem, and my computer several times and reset the router to factory settings to no avail. I thought it might be a problem with comcast (maybe the storms knocked something out) but the modem is working fine; TV and phones still work and all of the lights on the modem box (power, DS, US, Online, ect.) are still on. I called comcast and they said they have registered no issues in the area.

Right now I'm connected to the internet through the modem. I have absolutely no idea what the issue is. I've tried everything I can think of so I'm hoping somebody can help me out. Hopefully I don't need to buy a new router.

Here's everything I can think of that might help solve this:

**additional notes: Router light is solid orange when plugged in and connected to modem. Light is flashing orange when plugged in but not connected to modem. Upon resetting or unplugging and re-plugging power adapter, light blinks blue for ~5sec, then is solid blue for ~3sec, blinks again for ~5sec, then turns solid orange.

Hi, I'm not an expert , but if you can access the internet through the modem then it seems the problem lies with the Belkin.

Question: can you still access the Belkin admin panel through a wired connection? If so check all your set up settings again (since you restored it to default). {I'm assuming here you know how to do that part.}

[downtime]

I don't know why it would only happen after three weeks, but in the router find the setting to clone mac address and apply it. Worth a shot.

[BDP1397]

2nd thought: has your service provider changed your settings to only have 1 mac address / ip address assigned?
If they did then your router would stop working unless
1) clone your mac address , as downtime said or
2) tell your service provider to unblock the mac address so that you can set up a wireless router in your home.

Ask your service provider about this.

I can still access the admin panel - actually I can still do that through the wireless connection. Still no internet though . Everything appears to be normal in the settings. here's the front page:

...Tried cloning the mac address as suggested - no apparent change. Tried rebooting again, but still no change. In the mean time I'm going to try to contact the service provider and ask about unblocking the mac address.

NAT not working. No default route also.
So, you pluging same cable to PC, and receiving IP. Same cable plugged in Yellow port on Belkin.
Which WAN port status do you see in Belkin setup via browser? You should see in status same MAC address (00-26-B9-1F-A4-45) if you complete MAC clone procedure, also your WAN port (yellow) should receive same 24.10.100.119 IP address. Please login to router and check this.

[BDP1397]

I didn't see any Wan settings.

WAN IP NULL
Subnet Mask NULL
Default Gateway NULL
DNS Address NULL

Have you tried running the setup wizard after you rebooted from restoring factory default settings?

If your provider is Dynamic connect, it should give you the needed settings automatically.

If not, have they given you the settings mentioned above in a service contract written somewhere?

[downtime]

Try another cable from router to modem, and see if there's an update for the router firmware.

[BDP1397]

You said..'Right now I'm connected to the internet through the modem."

This would imply that the Modem has automatically assigned your computer a working IP. So it's working as the DHCP, not the router.

Is this assumpation correct or did you enter settings on your computer to use the modem to accesss the internet?

If the Modem is working as a DHCP, and you want the router to do this instead.

Can you access the admin panel or the MODEM?

If you can, there will hopefully be a setting somewhere in there under (WAN,LAN,DHCP,) that allows you to turn off THE Modems DHCP and only work as a modem.

Then you can go into the ROUTER admin panels and point the WAN Settings to the modem for connection.

[BDP1397]

In here "Can you access the admin panel or the MODEM?"

I meant ON the modem
