Wireless connection for slow. At a loss for ideas.

by vanvleettv / August 3, 2012 2:10 AM PDT

My wireless connection is very slow (<1mbs). I have a linksys e1200 router currently and have tried it the connection out with a different linksys router as well so I don't believe it is the router. When I connect the computer to the router with a ethernet cord the speed is great (>26mbs). I don't know what this could be. I have powered off all the devices (modem, router, computer) but still get same result. Any ideas? Could it be the modem? I have Comcast as a provider and an RCA modem (model: DCM425).

Thanks in advance.

I looked into changing the channel but did not work. I know it can't be the laptop either because it works on other wireless connections and this same problem happens on multiple devices with my connection.

As long as you know it's not the laptop or the router then what to do next?

There are issues with drivers and some routers and some routers with some settings. I don't think I can help if folk dismiss the router as well as the laptop.

Maybe in such cases, it's best to call in the folk that does your tech support at home and let them at it?

I tried the suggestion of the channels, same result.

I have tried multiple devices over this connection all with the same problem.

I have used this laptop with other wireless connections and it worked fine.

Could it be the modem? I wouldn't think that would have anything to do with it. Or would it be something Comcast would be able to change?

To me that tells me it's the router.

But you seem to dismiss it's that and want it to not be that.

The new clue you gave points me at the WiFi router. It could be out of date firmware or settings. But as long as you maintain it's not the router and I can't see the firmware version and settings I can only offer guesses and that guess is going to be the most likely and nothing more.

When you are open to it being the wifi router, then a discussion can start. Also, there can be a comcast issue but if it's the usual comcast MTA then I would not be looking at comcast.

i fixed the issue!!! Here it is if anyone else has this problem.

This is for a linksys router E900 or E1200 (don't know if other routers would be similar or not)

Go to and login to your router. If you've never done this, look for instructions that came with your router or do a google search to find the default username and password.
Find a page that has QoS settings. For the E1200, you need to click on "Applications & Gaming" and select the "QoS" sub-menu.
Disable WMM Support.
Click save.
