I'll explain as best I can, but I wasn't there when the problem started.

Home network;
Line in ->
Cable Modem ->
Netgear Network Switch Hub->
(Two computers, blue-ray player, Linksys WRT54GL)->
Linksys then gives the wireless to the house.

(I THINK that's how it was. It's remotely possible that the Linksys was between the HUB and the modem, but I doubt it)

A small electrical storm came through the other day and my fiance said that the wireless was out. The computer hooked into the TV still worked, though (hard wired to Hub). I unplugged and unhooked everything, but that didn't solve the problem. I connected everything as listed above (with Linksys after the Hub) but still had only the hardwired items work (I assume all of them, but only tested one). Resetting the Lynksis did not help.

I brought my laptop from work home and connected it with cat-6 to the Hub as I always do, but the laptop would not connect. I kept getting "Unidentified Network", and "Local Area Connection doesn't have a valid IP configuration". I could never get any internet with the laptop. The lights on the Hub and the Lynksis show that data is being transmitted and wireless is active, but I still could not get any wireless (tested on two computers and cell phone) or a wired signal through my laptop.

I tried;
Laptop, to Linksys, to Hub, to modem
Laptop, to Hub, to modem
Laptop, to Hub, to Lynksys, to modem
Laptop, to Lynksis, to modem
Laptop, to modem.
Nothing worked.

Just to cover all bases before I bought a new wireless router, I brought my Lynksis to the office. The Lynksis was able to get internet right away and began transmitting wireless. My laptop was able to connect fine through a cat-5 and wirelessly.

So, the issue isn't my laptop, or the Lynksis. The issue seems to be how the Lynksis wants to play with the internet at my house (but also issues with my laptop at home). Does anyone have any ideas? I read in one of the dozens of posts I checked last night that someone needed Time Warner to reset the system on Time Warner's end. Does this sound plausible? How does that explain some of my hardwired computers still working?

Thanks for any input
