Ok, I know networking, and this has even got me pulling my hair out. Doing this for a friend. They had a linksys wireless router hooked up all summer and it worked fine they said. Then it went down.
The devices in question is: Sprint SP-645M-A1 DSL modem/router, and Linksys WRT54G V3 wireless router.
I did the following:
1) Set the Linksys router's IP address to 192.168.1.10 from 192.168.1.1. (because the sprint modem was 192.168.1.1, so I figured they would be conflicting)
2) Manually put in Sprint's DNS server IP's in the Linksys router as it was not picking them up from the Sprint Modem/router.
3) I also had updated the firmware on the linksys before all this.
I have not updated the Sprint firmware, not sure how to do that either or find the files for it.
I dont' understand why would it work for several months, then quit? Why would it even work at all with the same IP's on both devices?
The Linksys works great on my Cable modem, so I think it's working fine. But when on the sprint modem it doesn't. You can reset everything, renew ,etc and it will work for a while, then 5mins later, nothing. Sometimes you can ping places and resolve dns, but not get to a website. There is one ethernet connected PC, and one wireless laptop connected to the linksys. Tonight when I came to work on it, I could not even get the linksys to respond via http, I had to reset it.
When you connect the modem directly to the desktop, it works great, and is very fast too.
It seems the Linksys doesn't like the Sprint m/r or vise versa.
It worked fast and responded fast on my cable modem (I have a linksys myself on my cable modem, without the wireless too.)
Am I missing something here? Whats going on, and why does it work for a short bit then go down? I did a full virus/spyware scan on both comptuers too BTW. I did change the MTU on the linksys from "automatic" to 1500 before I left tonight, as that's what the Sprint m/r is using. Not sure if that will make a difference or not. I'm out of ideas...
Any help would be appreciated!!
