With only ten feet away, drop of signal because of distance isn't a serious
consideration.
However, what Tim wrote does: If there is another modem operation on the same frequency,
it will cause interference (like the old moiré patterns from physics-class)
If they use hidden ssid, it might be a bit harder to detect, but, moving them 4 channels
up/down might be helpful, just like moving to the 5GHz band:
- those signals dampens more when they travel, thus causing less interference
- on the 5GHz band, you can use consecutive channels with less problems, on 2.4 you have
serious overlap.

sean darcy:
I'm about 10 feet directly across from an n wireless router. And
what
you describe happens 2-3 times a day. Never on my wife's windows laptop.
BTW, I don't reboot, just disconnect and reconnect.
You could be in a dead spot for wireless reception - reflections of signals around the
room you're in merge and cancel out where your computer's antenna is located. Try
moving position a bit. I can produce this sort of problem when just a couple of feet from
an access point.
You could be using the same WiFi channel as a neighbour, and the clash of each others
signals messes up yours. Try changing your access point's channel. I've had that
problem, too. Changing channels made a world of difference. I wish the interface that
shows your nearby networks that you use to pick the one you wanted showed what channels
were in use, rather than having to use some other debugging tool. It'd make setting
up your wireless LANs a lot easier.
Some access points have an automatic option for them to pick which channel to use. Mine
always automatically picked the worst one to use.
Logically speaking, it'd be scanning nearby networks, and avoiding channels that are
in use; or, for where they're all in use, opting to re-use the channel with the
weakest signal, presuming that it was the furthest one away. However, there's a
fundamental flaw with this process - the access point can only determine best and worst
channels for itself, your clients are in other locations, and which already-in-use
channels are stronger and weaker, for them, will probably be a different set of channels
than the access point's.

All mail to my mailbox is automatically deleted, there is no point trying to privately
email me, I will only read messages posted to the public lists.
George Orwell's '1984' was supposed to be a warning against tyranny, not a set
