![]() ![]() It seems very likely that it is related to DFS as in this region (New Zealand) the DFS band starts from channel 100 as you can see below (taken from the official site ).Īlthough like you say if DFS was unsupported on the TX50E I should not be even able to see my 5GHz wifi on channel 100 which I am able to do and even connect to it although it quickly loses internet and local network access. ![]() I do not believe this is an issue with interference as my previous TP-Link wireless N adapter (TL-WDN4800) had no trouble with channel 100 to 128 in the same computer although it uses an Atheros AR9380 chipset and not an Intel AX200. You can see the router channel list below for an 80MHz channel width:Īs you can see transmit power is already at 100%. ![]() I am using an ISP (Spark) branded Huawei HG695b ac router with 20/40/80MHz channel widths (). I think a proper explanation of why the TX50E cannot use channel 100 and above is needed as it seems unlikely that the onboard Intel AX200 chipset which is designed for ax 160Mhz channel widths that require as many available channel blocks as possible would have such a I am unable to try any channels above 128 as for some reason my router doesn't list them. I prefer the higher channels like 100 because they seem to provide better signal penetration through walls. It is my understanding that all Wifi 6 products that support 160Mhz channel width require DFS support in order to work. Even my ancient TL-WDN4800 seems to have DFS support () and ran perfectly fine on channel 100. If they mean the Intel AX200 chipset on the TX50E cannot use channels like 100 and above due to DFS this (AX200NGW) seems to suggest otherwise under Flags "DFS (slave)". I suggest you change the channel to a channel that you can use if you don't have special needs." If the above does not work, may I know the model of router, and a photo of the 5Ghz wifi settings on router, and also the motherboard information of your computer?įrom your description Channel 36.40.44.48 works okay but have random slow down, is this the reason that you prefer a higher channel got the following reply from Tp-Link Technical Support: "T5E does not support 5G channels over 100 when the chip is manufactured, so it will lead to the situation you mentioned. At the same location of TX50E, please connect to the same 5Ghz WiFi and test performance, does other device perform better at the same location?.For stability, you could try lower 5Ghz channel width 40Mhz.Turn off Wireless Advanced settings on router like Band Steering, Roaming Smart Connect Whole home Wi-Fi etc.Here is a brief introduction on DFS channel : Tīand 4 channels on the main router (Channel 149- 165) are more recommended as DFS channels are also used for radar and could be unstable It is recommended to scan for 5Ghz WiFi channel using WiFi analyzer app or software and select a better 5Ghz channel. ![]()
