Hi Guys, I've been plagued with some terrible Wireless performance the past few months. I found these forums and have improved my situation a little but could still use some advice. I am currently running Merlin's latest firmware on my RT-N66U. I followed this post to a T: http://www.snbforums.com/threads/guide-troubleshooting-wifi-issues.12825/
I had been running my Asus for about 1.5 years without issue. Recently, my 2.4GHz and 5Ghz wireless performance has become worse and worse. I get 1-4Mbps despite having a 75 megabit connection. When I run a speedtest.net from a wireless device sometimes it will spike to 5Mbps and then quickly drop to zero. My LAN devices get great performance. I flashed my firmware to Merlin about 2 weeks ago and did a factory reset after. Since then my N/5ghz network has been rock solid. My G network is sadly still really crappy despite playing with different channels and positioning of my router.
One crazy theory: too many wireless devices? I have about 25 wireless devices connected at peak times. Is there a threshold?
Another theory I had was old/legacy devices impacting wireless performance. I have some old foscam wireless cameras and some wireless lightbulbs all using my G network. To test this I gave my G network a new SSID and only connected my iPad and Laptop. Both still reported terrible speeds and performance.
Neighbors: I live a town house and can see 5-10 other networks at any given time. I have used an SSID scanner and found the least common channel to use but that doesn't seem to improve anything.
One last note: when I run a speed test from a hardwired device I noticed my CPU on my Asus spikes to 100%. Is that normal?
Is it time to replace my hardware or am I missing something obvious to try? Thanks in advance for any guidance.
