Upgraded and my router went to sh*t:

It happened occasionally before where I would lose connection but now it's really bad. Getting to the admin console is rare.
Dirt (great name, by the way. No joke), have you tried taking your router out of the closet? (no double entendre intended). Do you have stainless steel studs in your walls? Do you live in an Airstream mobile home? (the one with the aluminum skin)
I'm having issues as well, ever since updating to 1.31NA on my A3 revision.
Jon, have you noticed whether or not your problems arise at the same time of day, or are they sporadic?
Do either of you have your routers placed near equipment that produce a lot of electromagnetic interference? Perhaps an aircondtioning motor on the other side of the wall, you live underneath high voltage transmission lines, your next door neighbor is a ham operator, your next door neighbor runs a hydroelectric power plant? Ok, sorry about that last one.
I know the both of you stated that the problem got worse after the flash upgrade but you were having these issues before the flash but not to this extent. Is that a true statement?
Forgive me if you think my questions are sophmoric. I'm just running over some things I'd try if I were having the same problem since I can't see exactly what your setup looks like, or whether you installed or unstalled software lately, or new drivers, or you changed some setting on one of your Windows services, or something - anything. Is your wireless setting set to "Always on"? Transmission rate set to "Best"? Channel width set to "Auto"? Auto channel scan enabled? (This particular feature is amazing. Everytime I reboot it never fails to select a channel that NO ONE else in my neighborhood is using) These are my settings and they work well for me. If yours are the same, well - hmmmmmmmmmmm.
When I look at my site survey I often see a neighbor's router pumping out a stronger signal than me and he is over a hundered feet away. But, I suppose that this should not have any effect on me if we are on different channels. Do you guys always select the same channel? I have noticed at times that I lose a bunch of signal strength every time my wife decides to come out to the garage (where I am) and talk on our 2.4GHz wireless handset. Other times the signal strength almost completely dies and I cannot figure out why but it is usually during the same time of day because when I crack the top on my laptop in the morning the signal is loud and proud. Don't kill me for this one but are your NICs Wireless G or Wireless N? I have a wireless printer that is Wireless G and one day I could not get it to connect until I figured out that while I was "playing around" with my settings I decided to check the "WLAN Partition" box in Advanced Wireless. It was one of those "Ah HA!" moments when I read the help file for that feature a second time. I discovered in real time that I had turned my wireless AIO printer into a very nice looking printer paper storage unit. Of course, UNchecking that box restored balance to the universe as sunlight came streaming through the windows, rainbows appeared and a unicorn went strolling through my living room. OK, I digress.
Just tossing a few bits of my stream of conciousness out there. Only a few though. I'm running out.
