Hi,

I'm having problem with my Deco M4 wifi 5 ghz. I'm formar user of Archer A9 AC1900 and I recently purchased Deco M4 v2 pack of 3. After setup I couldn't find wifi 5.0 because my deco M4 units automatically connected with 5 ghz channel 40 which is not supported in my country (Bangladesh). I can only use UNII-3 channels in my country and I can't find any way to manually change it in my deco units. I think this is the most essential option to change wifi channels which I don't find in my deco units. Without UNII-3 channels, I'm limited to use wifi 2.4 which is slow and very congested in my area. So now, after an expensive upgrade to a mesh networking system I get even slower speed than my previous Archer A9 system. Is there any way that I can use my deco units in UNII-3 channels? Please, help me and solve my problem. Regards
