The antenna for built-in wifi in notebooks is usually in the
screen/lid -- adjusting the screen angle and rotating the computer on
the desk seem sometimes to help with wireless performance on my netbook.
  I've recently purchased a USB wireless adapter for one of our home
machines -- I haven't had a chance to try it yet; I'm pretty sure it's
made by NetGear.  In the past I've used smaller USB wireless adapters --
looked like fat thumb drives -- from NetGear (worked very well) and from
AirLink 101 (can't recall that it ever worked).

  (I've had negative experience with AirLink 101's wireless routers, so
it has been a few years since they got any more of my money....)

Subject: [PCBUILD] USB network adaptor
From: Peter Shkabara <[log in to unmask]>

My daughter's laptop (a new Sony Vaio Z) is having problems with the
built-in Intel Centrion N 6230 wireless adaptor. The older Vaio Z that
she
still has works fine, but the new one works fine for a while and then
becomes VERY slow with speeds of 14kbps or so.

 

I am considering getting her a USB network adaptor to circumvent the
problem
and am looking for recommendations for such a device. Obviously, small
size
is helpful. Newegg shows various brands including Intellinet, StarTech,
Roswill, Asus, and Encore. Problem is that reviews show all to have good
and
bad ratings. Any feedback from the list would be appreciated.

 

If by chance anyone has a solution to the Centrino adaptor problems,
that
would obviously be even better. So far I have tried new Intel drivers
and
adjusting the networking settings with no improvement. It may work well
for
several hours, and then drop speed for a long time also. Did try
changing
the router frequency to no avail. Interestingly, the signal strength
shows
as being very strong even when speed is slow. PING times to the router
are
50 to 1000 ms or even timeout when it goes in the slow mode. The router
is a
D-Link DIR_655 in case that may matter.

 

Thank you.
