DD-WRT firmware for TPLink WR841N v9

by salilsurendran / April 9, 2016 4:50 PM PDT

I have ATT uverse broadcasting in 2.4GHz. In my living room I get close to 4 Mbps download speeds on my desktop computer and my signal strength is -57db. In my bedroom I get 13 Mbps which is the full speed with the same signal strength. There are many other wifi signals that are causing interference in my living room. I have a TPLINK WR841N v9 wireless router which supports 802.11 n. I see two options:
1. Have the TPLink router broadcast in 5 GHz? Is this possible with the DD-WRT software?
2. Use the TPLink router as a Wifi repeater and have a wired connection to my desktop computer in the living room

I was wondering as to what would be a better option and if so what would be the right DD-WRT build to use for this?

Already changed channels

Already changed channels to 11 which is supposed to be least crowded. But no help. Have been using Xirrus Wifi analyzer as well to figure out what could be done.

The problem is not with the router

In reply to: ROFLMBO!!!

The problem is not with the router. The ATT Uverse router is the primary signal, I would like to use the router as a wifi extender. The same router worked very well with comcast but the internet speed there was 50 Mbps and with ATT it is 12 Mbps. It is just the spot of the living room where the desktop computer is kept is very crowded with wifi signals interfering with each other.

Extenders drop the speeds.
by R. Proffitt Forum moderator / April 9, 2016 10:21 PM PDT

So we know that up front. Now if you were to use that router as a WAP, then you've avoided the old extender speed loss issue.

As to your comment about crowded, etc. If you have many devices using the internet, they share that speed. Nothing wrong about that and it's not interference.

Sharing wifi signal is not the problem
by salilsurendran / April 10, 2016 5:37 AM PDT

No the problem is not many devices sharing the same wifi. Like I said I get full speed at every other place in the house. but many different signals interfering with my signal.

Then fix that.

You know the issue now. You control those devices so rearrange, use channels or bands to make it work. If it's the neighbors then only a band change may give relief.

It seems you know what to do so I'm sure you'll get it done soon.
