I'm running Windows 7 Home Premium on my desktop computer and have had
a household wi-fi router setup for some time. A few weeks ago our
power line took a lightning strike and the surge from this knocked my
wi-fi system out. I have tried two replacements but can not get the
connectivity I had with the old Netgear setup. My wife's kitchen
computer, running Windows XP, will not hold a connection more than a
few minutes. This computer is downstairs and around the corner of our
L shaped house.
What is the best wi-fi router choice in terms of signal strength and
stability?
Well, signal strength is a fun topic and all, but it not the
only element to making Wifi work.
http://en.wikipedia.org/wiki/802.11
802.11 b and g, are the older standards for Wifi. A higher
performance standard, is "n". But when buying "802.11n" devices,
some were "pre-standard" designs, others "post-standard". So some
were designed, before the standard was finalized.
If you mix b/g/n, they're designed to compromise their operation,
so they all work. The "n" will only use 20MHz channel spacing,
if other "b" and "g" things are detected. There's probably an
article about what happens, when they're all present and running
in the same space.
You should review the hardware bits and bobs you're trying to run
with the new router, to see if you haven't been making trouble
for yourself. From a standards point of view. If the kitchen
computer uses a "pre-standard" 802.11n, perhaps you could change out
the adapter.
To eliminate "range" as an issue, you can experiment with moving the
affected computer, either close to the router, or far from the router.
If the problem is not enough signal strength, then "close" will help.
If the problem is too much signal strength, then "far away" might help.
Most people assume "I need an antenna with lots of dBi on it, to
crush the router", and it isn't always a "more is better" situation.
You can have radio reflections and multipath, depending on the reflective
surfaces in the area.
I'd start by making a list of the make and model of all the
Wifi gear, then Googling to see if some are known stinkers.
Some single-chip USB Wifi adapters, have quite variable radio
sections, such that the signal strength unit to unit has quite
a bit of variation. (Some people report good results, some report
bad results, and it's the quality control on the chip that is the
issue.)
