I hope that someone can save themselves some pain and suffering from my ignorance yesterday.
The quick backstory: We had to clean out our master bedroom as we were getting new furniture. Thus I had to move and unplug our DSL modem, 2 routers and a DECT 6 phone.
Fast forward to the evening and it's time to reconnect. I set everything back up and plug it all in. Lights are on, it all appears okay. I did notice the modem lights were going nuts, but I didn't think much of it at the time.
Later in the evening I turn on my computer... no internet. So I run upstairs and check everything. I figure the wireless router jut got reset. After a fight with my laptop (the teenager managed to wreck the network port, but that's a rant the wife heard) I was fed up and went to call Telus. That's when I found that along with the routers and modem that the new phone wasn't working.
At this point I checked the cords between the modem and phone. I switched them and low and behold the modem and phone started working again. But I STILL couldn't get any internet from the wireless modem even plugged in (it would work find from the wired, but I needed to login to the wireless).
So, for the heck of it, I switched the power on the routers... well damned if that didn't work. I managed to login to the router and set up my wireless again (still not sure if the 360 and PS3 are still working, but that's tonights job).
I kinda felt like an idiot after it was all said and done, but I chalk it up to a learning experience.
