Its called dynamic rate shifting, the further from the router/ap you
get it drops the speed to maintain
a reliable connection. Other reasons are bit errors caused by
interference or a variety of
other causes. If the error rate is high it will continue to drop all
the way to 1mbs until it has a reliable connection.
Might try repositioning your ap or the antennas.

Thanks for the info. Theres another problem is that after a night long,
although WiFi is well connected between PC and AP with very good signal, I
couldn't get connected to the internet untill I turn off and back on the
router/ap (DI-724P+)
again. Is there any time setting i miss out which stop the router from
working all night long ?

Thanx again.

I've not been around long enough to know what brand that model number
applies to but...

In googling around for the better part of a month before buying a WiFi
setup about 6 weeks ago I found lots and lots of problem with wifi gear
overheating. Seems the thermal design is waaaay out there. My LinkSys
USB client unit is that way. It'll run fine on the desk but let even a
ray of sunlight hit the case and it's outta here. Same if I leave it
sitting on top of my laptop. The big ASIC chip is the culprit in my unit.
I foresee a hole in the case with a heatsink poking thru :-)

I'm having a similar problem with my Netgear WG511T CardBus card in my
laptop. This Dell Inspiron 4150 runs rather hot when it's busy, warm
enough that the card will shut down after awhile. If I leave the top
CardBus slot empty and aim a fan at it, things are fine.

Check your location and see if things are too hot. Anything about room
temperature should be suspect.

If it's not temperature and the latest drivers don't fix the problem, take
it back. If that doesn't fix the problem, take it back again and get
another brand.

Most systems have a time setting/delay for hard disk/system/screen
hibernation/shutdown etc. go into power settings and set everything to never
turn off, try it for that night and see what happens.

There is a definite problem with the system hibernating while connected, and
then powering back up with the old settings.. Sounds like you may be running
into that when it sits overnight/long enuf to go into power save/hibernation
etc mode. Laptops are usually set at a very short active time before power
save, but even desktops power save after a few hours.
