I have 6 wireless devices at home: Toshiba laptop with Windows 7 Home Premium x64
pre-installed, Dell Inspiron ONE 2320 with Windows 7 Home Premium x64 pre-
installed, an iPod Touch gen 3, Acer laptop with Ubuntu Linux 11.10, my wife's
Android Blackberry 8230, and a Sony Blu-Ray DVD player. All of these devices--
except my 2 Windows 7 boxes--connect to my wi-fi flawlessly, and they stay
connected without error.
The two Windows computers go through this cycling process of connecting and
disconnecting every few minutes (many times per day). Sometimes just clicking on
my wireless connection in the lower right-hand corner of the screen with the
little yellow triangle with an ! in the middle, clicking disconnect, then clicking
re-connect fixes it. Sometimes I just have to walk away and do something else for
either a short while or a long while, and it will have resolved the problem
When the 2 Windows PCs have disconnected and are taking a "longer" time to
reconnect (10 minutes), I can at that moment walk over to my Ubuntu laptop or pull up my iPod and get online and stream video or whatever. Or I can stream Netflix to my DVD player or I can browse the web on my wife's Blackberry--and I get the little
arrows that show it's using the wi-fi and not the cellular connection.
I have gone into the properties of the network adapters and have deselected the
checkbox that says "Allow the computer to turn off this device to save power." I
use the High Performance power option, anyway, but I still have made sure that box
is not checked.
I have downloaded a utility called inSSIDer to see which wi-fi channels my
neighbors are using. They are all using channels 2 or 6. I am using channel 11, so
there's no overlapping of signals.
In my house I have two 900 MHz phones--which shouldn't be a problem--one of which
is 12 inches away from the Dell I'm having trouble with. I can unplug them and
remove the batteries from the phones and the wi-fi problems still persist. I also
have a microwave about 15 feet away from the Dell, but I never use it. I have not
unplugged it, but I don't believe it's a problem, even though it can use the 2.4
I can shutdown or unplug all other wi-fi devices in the house and the Windows
computers will still have the problem.
I have two wireless routers in my possession--which are NOT plugged in at the same
time--that I have used for troubleshooting. One is a Netgear N600 and the other is
a Cisco EA4500. The problem persists no matter which router I plug in. I have set
them to factory defaults and I have tinkered with them to an extreme, carefully
trying one setting after another. Still, the intermittent connectivity problems
with JUST the two Windows boxes persist.
I run Microsoft Security Essentials and SuperAntiSpyware on both computers. There
are no viruses, there is no spyware.
My LMHOSTS file is clean and I have flushed my DNS. Still, I have problems.
I am using WPA-2Personal security, using AES encryption on both computers. I have
tried WEP, but I don't want to use it as it's insecure. WEP did not help. I have
not tried using no security, as I don't think this is a viable option. Having an
unsecured network is unacceptable.
I have tried using DHCP and I have tried using static IP addresses. Neither option
seems to matter and the problem happens either way.

What is going on? What have I missed?
