~E3200 Router
~Purchased about 1 month ago
~Same firmware since arrived
~Comcast 20M down internet
I bought this E3200 about a month ago and has been working fine since. I mostly use 2.4Ghz channel. Both channels are open. Most of my devices are connect by wireless to the router using 2.4Ghz.
I am not getting full bandwidth with wireless through the router. I have turn the 2.4Ghz to only 20mhz under Channel Width channel and have gone through every channel and currently have it set to Channel 2.
When I run Speedtest, the most I get is15.5M down. When I connect another router to the internet and use the same device, same channel, same Speedtest location I am getting 23.5M down.
How can I increase the wireless speed on this router?

Are you testing from the same location? Also make sure you have the latest firmware. Another good thing is to make sure that WMM is enabled in the QoS tab, because that being off could result in the adapter picking up a G instead of N signal which equals lower speeds.
One other thing, what is the speed when you're right next to the router?

WMM was already enabled and still enabled.
Downloaded the latest firmware and updated the router. Did speedtest again on the same device and nothing has changed. Get about 16M down.
I am testing on a laptop right next to the router. Same location.
Any other suggestions?

Have you updated the wireless adapter drivers on the computer?? Make sure you are using WPA2-AES encyption also.

Computer has the most current driver. No changes have been made on the computer when I test this router next to another router.

In order to take full advantage of the speed and range that wireless 802.11N has to offer, both router and adapter must be wireless 802.11N capable. So, check the wireless computers that you have are N-capable adapters.
Did you try making any changes on the router except playing around with the channel to fix the issue? If not, please try this. Launch Cisco Connect. Click on router settings and then click on 'advanced settings' and click ok.
This will open the router's web interface. Click on the wireless tab at the top. Then click on manual. After this, Lower the MTU (Maximum Transmission Unit) from 1500 to 1400 or less (usually found on your routers main/ basic setup page). Here is the link for determining and setting up the correct MTU size: http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=
Then click on Security tab disable SPI Firewall Protection, uncheck Filter Anonymous Internet Requests...
Then check the connectivity status..

Did all the above steps and still the same speed.

Move the router off the floor and away from walls and metal objects (such as metal file cabinets). Many cordless phones, microwave ovens, baby monitors, garage door openers, and other wireless electronics also use this frequency. If you use these wireless devices in your home, your computer might not be able to "hear" your router over the noise coming from them.
