[opensource] DD-WRT bridge and OSU wireless

You can either have it sent back (presumably under warranty), get a new 
wireless card on your own, or try bridging an osuwireless connection 
with a router or something. What you choose to do is your choice, and 
your choice alone. Whichever you choose will have its advantages and 

Keep in mind though, if you try to bridge your connection you will be 
taking a risk. It's even worse now because I guarantee there are people 
from OIT reading this debate, so they'll expect you to bridge 
connections knowing it's not ok. If they aren't listening, they can also 
see permanent archives of our communications online. Whether or not you 
propose doing this is your business, but it is not representative of the 
Open Source Club nor is it supported by us.

Personally, if I were you I'd just look for network cables to plug my 
computer into. Different departments have different policies about 
plugging in laptops, so that's something else to be aware of. I should 
note here please do NOT try this in our office as the CS&E department 
will disconnect the port as soon as someone tries that. There are other 
departments who also have brain spasms about stuff like that, so just 
something to keep in mind...

I know it sucks to be in this bind. I've been there myself, without a 
computer for a few days (I get the in-home service warranty for that 
reason). It also really sucks when your wireless breaks, especially 
since they pretty much want you only using osuwireless for network 
connections everywhere. May as well be a dead laptop when that happens. 
Good luck with whichever route you take.
