How to Fix Linksys WRT 1900 ACS poor upload download speeds

If you’re like me, you purchased this router expecting improved wireless coverage as well as improved upload and download speeds close to what your provider advertises at least. To my surprise after installing this refresh of the classic WRT routers of years past I did notice much improved wireless range however my upload and download speeds were pretty poor, actually worse than my previous 5 year old Apple router. After hours of digging in the menus and of rolling firmwares back, I finally found the magic fix.

The stock setting for the 2.4 and 5 Ghz channel is auto and this is the issue. It most likely selects the most common channels that all router manufacturers like to use and this in turn causes major wifi congestion and thus slow speeds.

If you change the Channel setting of both the 5Ghz and the 2.4Ghz channels to the highest possible setting which is channel 11 for 2.4 Ghz and 161 for 5Ghz, you will see a significant speed boost as I did. I left my 2.4ghz channel on auto as I do not use it much but 5Ghz now sits on 161 and its blazing fast, hope this helps and if so please leave a comment.

Cape out!
