NWA50AX PRO random download rate limiting

Phil_M

I have a simple setup of 2 x NWA50AX PRO connected via cat 6 ethernet to a Linksys MX5600 router. ISP speed is 900Mbps up and down. Each AP is running standalone, with one 5MHz channel set to ch 120 and the other to ch 36, both at 80Mhz and -20dB output. WiFi speedtest at the router is solid 1Mb/s down and 900Mb/s up. this has never varied over the past 3 months. The same speedtest via the APs occasionally hits 850Mb/s up and down which is obviously good but more often tops out at around 550Mb/s down and 850Mb/s up. 5MHz channels do not change between good and bad results and WiFi analyser confirms optimum channels in use. I have tried setting channel width to 160MHz and increasing transmit levels with no improvement. Rate limit is off. Any ides?

Hi @Phil_M ,

I think you can check these FAQs first to optimize the WiFi performance:
