Wireless connection keeps dropping off

Have a laptop with a centrino processor, after it connects with the router at
home it drops the connection in a minute and shows a red X on the wireless
network connection. There are 2 other desktops on the same router and the
motorola 220 router shows 5 bars on the wireless network connection, but does
not connect again. When I am on the road it works fine at a hotel. Could you
please help me.

You don't say if you are using authentication. If you are using WPA this is
a symptom that has been experienced by others and there is a registry edit
on my blog. If not, you may be experiencing co-channel overlap with someone
else's AP. Please check your configuration against the following article:

Hi
Might be excessive noise form 2.4GHz phone or similar device.

Jack, Great point, I do have several 5.8Hz phones around. I will switch them
off and see. However the other two desktops have the 5.8Hz next to them as
well!

5Ghz devices will only affect you if you are using 802.11a, as you say a
number of devices operate within this band and can cause noise.

802.11b and 802.11g use the 2.4Ghz band. Devices such as microwave's
contain magnetrons which operate within this band (mine operates at 2450Mhz
= 2.4Ghz), they can cause interference but are quite well shielded. Other
wireless devices also cause noise within this band.

You can use Netstumbler to gauge signal-to-noise ratio (SNR). Again, this
is covered in the article I referred you to earlier:

With 802.11a stay away from channels 153 through 161.
Many US products don't even offer those channels...

I've got 5.8 GHz phones here and tons of 802.11a with no interference
whatsoever..
