View Full Version : Yet Another, fast on wired, slow on wireless (internet only)

So I have a WRT-160N v3 wireless N router with DD-WRT fw on it. When I transfer files from a wired PC to my wireless laptop I get around 8-10MB/s transfer rate.

On the internet side, my wired PC gets the full speed (I'm signed up for on comcast) 20/4 as you can see here:

On my wired win7 PC I get a constant speed of 2.5MB/s when downloading a large file.

Now, when I'm on my win7 laptop (which is right next to the wireless router) I get the following:

When I'm on the wireless laptop and downloading a large file the speed fluctuates between 1.3MB/s - 2.2MB/s sometimes it DOES stay at a constant 2.5MB/s, but not always.

I've tried everything recommend on this forum (tweaks to win7, tweaks to my router) and I can't seem to figure out why I can't get a constant speed on my laptop.

When next to the router I gett the following signal quality:

Should it be higher?

Search Google and see if the wireless adapter inside your laptop has the latest driver.
