I have a TP-Link TL-WDR3600, which is about 2 years old and several months ago my wifi speeds suddenly dropped to about half of what I am supposed to be getting and I have a 100/10Mbps cable connection.
DD-WRT had been installed for almost the entire time up until the speed issue and I never had any issued before. I have tried some of the more common troubleshooting such as resetting/re-flashing the router, switching channels and channel width to no avail, and I am now back to the stock TP-Link firmware I had before, but this has not helped.
It seems to be only the 2.4GHz wifi connection that is the problem on all devices in the house as I get full speeds connected via Ethernet from both the router and the modem and close to full speed on the 5GHz. My cellphone is the closest device I can get to the router and even when holding it directly next to it, I average about 35-40Mbps on 2.4GHz and 90-100Mbps on 5GHz
There are only 2-3 other wireless signals in my area and I am almost always the only one on my channel. There are also no unknown wireless devices connected or cordless phones that could be interfering.
Any assistance would be appreciated. Let me know if you need any additional info.
Thanks!
