Slow wifi with Archer A9
Hello,
I recently purchased an Archer A9 wireless router and I am having wifi speed issues. With ethernet I am getting 60-70 mbps at all times (which is what my plan is) so there is no issue with the ISP. However with wifi my devices are usually between 10-15 mbps, at times a bit higher but at times even lower, like under 5. I have tried reading online and changing channels/ width as well as disabling WMM but nothing has helped. I have also upgraded to the latest firmware and done a factory reset.
Any advice would be greatly appreciated.
Thank You
