Win 8 WiFi Signal Strength

Postby Major_A » Sun Mar 04, 2012 9:01 am

How do you see how fast your adapter is running? I can see the bars but that doesn't get to the meat and potatoes. 4 bars is worthless to me if my 300Mbps adapter is only working at 40Mbps.

See example:

The bars represent the signal quality, the speed below that is how fast the link is currently.
You can in theory get 5x full bars and a link speed of only 1Mbit.

The best (free) way to test network speed/throughput is using "iPerf" or "jPerf".
http://iperf.sourceforge.net/
I use it for modem testing in work. You'll need a second pc as it's uses the server/client model to work.
Don't change the defaults as incorrect options will give seriously slow results.
Tutorial here
http://openmaniak.com/iperf.php

To help poor signal issues, first change the following settings on the router.
Output power: This is easy --> 100% (Don't go higher if you have the option too!)
Channel: use 1, then 6 then 11. In that order, don't bother trying the other channels unless these don't help.
"netstumbler" (think its called vistumbler now) can show you what channels other networks are on.
"Fragmentation threshold" - Lowering this can help, drop by ~256bytes at a time.
"RTS Threshold" - Lowering can help, if you have interferance from other networks, baby monitors etc.
Drop by 256bytes at a time.
If you've no wireless G clients, set to N only and if not N clients; G-only.

The problem is I don't know how to see how fast the adapter is working in Windows 8. That's why I posted a pic of what I'm looking for in Win 8 (using a ss of Win 7). I went to download that program but Sourceforge wants me to create an account. First time I've ever needed to do that with sourceforge. I have the app Lan Speed Test but that only shows transfer speeds, not what my adapter is "running at".

Sorry, i havent tried Win8 yet and presumed that screenshot was from there.

You could try via command line

Code: Select all

netsh wlan show all

Open a command prompt and try the above. It's a Win7/Vista command and might work.

No idea... kenc51 is the resident network expert. But it can't be B or it wouldn't be working at 144 Mbps.

Most likely it's either a bug in the driver reporting b when queried by netsh, or windows 8 doesn't report it as an N adapter due to either a bug or just not implemented yet (it is beta afterall)

As Major says, he connects at >100mbps so..............

Sucks, thanks; but im far from an expert. Networking and supporting it on windows used to be my job.
Thankfully I've (almost) moved on from that, now work with dsl/fibre modems and sometimes get to work on some high-end production servers (Sun/IBM et al)
