So I had a Linksys WRT54GL but the problem I was noticing was that if I plugged directly into it I was getting 25Mb/s+ but wirelessly I was getting less than 10Mb/s. This was the same on my desktop and laptop, one with win7 and other with Win8, both with completely different networking cards. So I ordered a TP-Link TL-WR740N because it was cheap, had wireless N, and I could see if it was a router issue or something else. After hooking it up the same problem exists. This is all taking place in my apt within the same room, no computer is more than 15ft away from the router with direct line of sight. Any ideas what is going on?

What all do you have talking to the router over WiFi? If there are any B devices that is your problem. WiFi can only talk as fast as its slowest member, minus whatever correction for RF interference you are experiencing. To get the best performance out of a WiFi router...

#1. Only attach the fastest devices compatible with the router, in your case Wireless G. Disable any WiFi slower than that.
#2. Using a scanner like InSSIDer, review channel usage on your bandwidth, and if crowded, find and set your router to an empty channel.
#3. Configure your router / devices to use only the latest encryption methods. They are faster, and more secure than the old stuff.
#4. Turn off WPS if your router is so equipped..

I know advice to turn off /...

That's really not helpful, routers are more than capable of speeds greater than 10Mb/s wireless and more than capable of not reducing speed by as much as 300% over wireless.

I know advice to turn off / disable slowest devices sounds harsh, but it is well worth it. I bumped my brother in laws netbook off of my network (he had to get a dongle adapter to reconnect) but now my WiFi is cruising along at 150+ Mbps...
