Linksys router or @home problem?

[MOgeeks]

Hi,

I was using att@home for past three months with linksys 4 port router and everything works fine till yesterday. I cannot get any connection thru the router to any of the computer that is hooked to it.

I called @home support and they told me get get rid my router and connect PC directly to the cable modem and it works fine. They told me @home will not work thru the router with more than 1 PC, I need to get another IP address for each additional PC.

After ending the call, I tried to use the router and did not succeed.

I tried resetting the router and enter the information again and verified them carefully. By looking at the router setup, it appeared to be able to obtain IP information from the cable modem correctly as it display the correct IP/gateway/dns etc. However, PCs connected to the router cannot access the web at all.
If I link the PC directly to the modem, it works, but not thru the router. I tried disabling the DHCP in the router setup and it did not help.

Does anyone know whether @home has the technology to block broadcasting thru a router to PCs?
How can I find out if it is the router that is causing the problem?

I recently returned the leased cable modem and save a few bucks off the monthly bill and I wondered if there is any connection....

Thanks.

According to zoneAlarm, the DNS server of @home has been trying to access my PC from increasing port number,
is it scanning for something? it has about 50 alerts for 90 mins and keep on coming
can anyone help?
thanks.

My @home connection works through a router. Try obtaining a new router and see if that works. It may quite possibly be a router problem.

Try cloning your PC's NIC's MAC address on the router, that way they won't know you switched it.

athome is BSing you, to them you are using 1 ip address, the router translates that into multiple addresses, it is transparent to them. I would reset the router, see if that helps. If not, go through all the settings and make sure nothing has changed, check DHCP settings especially, make sure you computers are getting their addresses.

Yeah I agree that @home is giving you the runaround. Mine has worked flawlessly. I agreee with turbo in trying to reset to set it back to factory defaults. Also if you are using WinXP go to the network tab and try repairing. That's usually what what I try first. Also try rebooting the modem, router and pc's in that order.

I had that same problem as you. I have the SMC Barricade router. When I called SMC tech support, the guy said to disable ZoneAlarm. He said that there was no need for ZoneAlarm because the Barricade already had a firewall. I still use it though. Anyway, try disabling ZoneAlarm. I would also try AlphaStrike1's idea, it works for me.

A big thanks to everyone who helped


I got it working by changing the LAN IP in the router setup from 192.168.1.1
to something different and it works.

Now the question is: why did it work?
