Just a note – I personally did NOT find the solution to this problem, I’m simply reposting details about my problem and the solution I found on the linksys forums. I figure the more the info gets out there, the better. Plus, I seem to be good at getting results of searches to my site for my technical problems I’ve solved or found answers to.
First, we have Cox cable as our ISP. We normally have had great access with no problems. We have a Linksys cable modem and the Linksys WRT54G v2.2 wireless router. The problem started after a firmware upgrade. After the initial upgrade, things worked great for roughly a month and then we would completely lose all access to the web – both wired and wireless. Unplugging and replugging it in would work; I had to do a hard reset, reset security, etc. Things would then work for another month or so, and I’d have to reset everything again. Despite lots of calls to Cox support, there was no information or other suggested solution.
We bought a new wireless router that I kept in the box while I gave it one more shot. I started some serious googling and digging into the Linksys forums. I found I wasn’t the only one with this problem. After doing some reading, I found this thread that suggested downgrading the firmware. In particular, I used the link in the post by user “almuslet” that had a link to the proper version for me to download. Thanks, almuslet!
I returned the new router (unopened) and we’ve been running the older firmware for several months now without so much as having to even unplug/replug the router. Linksys screwed up their firmware somehow and moving to a “new” version was *not* a good thing. Maybe Linksys just wants to force people to buy a new router. No thanks – until all our laptops get N wireless cards, what’s the point?
