High net latency on Galaxy Tab S9?
For context my router supports WiFi 6, a TP-Link AX1800/Archer AX21. I'm on the 5Ghz AP with no other devices connected or APs in range, in front of the router, and I get 40 to 90ms on this tab. Somehow on my Legion Go (it's like a Steam Deck) I get around 1ms network / 1ms decode even behind walls.

TP-Link Routers Could Be Banned In the Next Year, Affecting Nearly 65% of Internet Users in the US
Same. I just wonder how long I was vulnerable to being part of a botnet because I didn't know the AX21 specifically had such a big vulnerability until these recent articles. I don't use the TP Link app so I don't get firmware update notifications unless I happen to log into the router. I Also picked

Poor video quality after new modem and router
Hello, after getting a new modem and router, when I stream videos on my computer, my video quality is poor, and videos buffer often.
I have Xfinity internet and had a free rental of the gateway (modem/router combo) XB7. Videos streamed perfectly! The free rental expired, so I bought a modem and rou

Deco X55 vs Archer AX21 + AC1200
I recently decided to upgrade our home Internet and initially connected the archer unit as a standalone, shortly thereafter adding the AC 1200 for a mesh system. This is virtually eliminated any dead spots within our 2000 square-foot home, however we are getting nowhere near the 800 MBPS advertised

Really Weird Issue Between Modem and Router
Good, thank you. I also seem to have gotten it to connect, but now my router keeps dropping connection (TP Link Archer AX1800), and, after running several speed tests, my speeds got progressively slower before it quit entirely. Modem’s still showing blue. Internet has so far been decidedly slower th

2.4 GHz extremely slow, 5 GHz great on AX21 (aka AX1800)
I am seeing very slow speeds on the 2.4 GHz band. Speedtest shows in the low single digit Mbps. 5 GHz is around 500 Mbps.
What I've done to troubleshoot. Selected the 40 MHz channel width (based off other posts). Chose channel 11; as it seems 'quieter' using a WiFi Analyzer tool. Rebooted the route

significantly lower than advertised speeds and connection issues using 3rd party router. Anyone have experience with using their equipment vs. 3rd party?
Using a TP-Link AX1800 WiFi 6 Router (Archer AX21) and recently purchased this thinking our older gaming router was the issue. We consistently have problems with connection and almost never get the 500mbps we pay for on any device. I have tested the connection coming from the wall and the speeds ar
