New 802.11n usb adapter, but signal weaker than old 802.11g 54Mbps adapter

I have a Huawei HG533 router, which is sending a signal to a new Cisco (linksys) AE2500 adapter
in another room, which is connected to an Acer PC. However the signal strength (in bottom left corner)
is only on 3 bars, sometimes 2 bars, and the speed is 13Mbps.

I have just bought the AE2500 adapter hoping it would provide a better signal than my very old
belkin adapter, which is 802.11g - 54 Mbps. When I use the old belkin adapter, the signal strength
is at 4 bars, and is is nearly walways at 54 Mbps.

Does anyone know why the signal strength and Mbps is so low on the Cisco AE2500.

Points to note: I use WPA2-personal AES encryption on Windows vista operating system. The channel is on Auto.
I've changed the channels from 1 to 11 and still it doesn't change the Mbps much, and is always below 54 Mbps.
I've changed the signal for around from using, g only, to n only, and b/g/n, and still nothing improves. Infact the g only is the best channel. The only time the connection goes to a high level of Mbps, is when I change the changing settings to 'n only' and whilst it is saving and the screen loads, for a split second goes to 144Mbps and has 5 bars signal strength, but when everything is loaded/saved, it drops to either 6.5Mbps or 13Mbps, and it moves to 2 or 3 bars signal strength.

Is the cisco (linksys) AE2500 adapter a good one to use with the HG533 router, or should I use another usb adapter instead? Does anyone know how to get the signal higher than 54Mbps in 802.11n mode?

Many thanks for opinions and help on this.

Depends on how congested the 2.4GHZ band is in your area, and if the Linksys is on either channel 1, 5 or 11 and what the second channel that you have it set for.  I have two Wireless-N A/P's.  One is set for Channels 1 & 5, the other for 7 & 11.  They are only 2.4GHZ, but I do not have a lot of congestion around me to cause problems, where as you may.


Download inSSIDer from http://www.inssider.com to find out how congested the airwaves are around you with other Access Points, then set the Linksys accordingly.  Also Wireless-N is going to be less distance, just like Wireless-G is less distance than Wireless-B.

Have you downloaded the appropriate drivers for the adapter from here ? I know in some routers, you can change the speed from 54mbps to 300mbps. Make sure there's not a setting in the admin panel for this.


Also I don't know if this is relevant to your situation, but wanted to post it just in case...


Huawei HG533 router speed issue

If you're using a Huawei HG533 router, you may have noticed that your wireless speed has started to decrease. This is especially common if you have a lot of devices connected to your router.

To return your wireless speeds back to normal, simply unplug the cable from the fibre port on your router and then reconnect it.
