Deco M4 5Ghz problem with latest firmware
Hi!
I have 4 Deco M4 devices, 2 of them V 1.0, 2 of them V 2.0. Since I upgraded them to the latest firmware (1.4.3 Build 20200918 Rel. 74289), some of my connected devices started to drop connections and became really annoying to use. For example, if I open a website on my phone, 4 out of 5 times it immediately generates a "network unreachable" or "could not connect" error. And even if it opens the website, the images or the CSS (style sheet) are not loading.
Many different devices affected, for example: iPhone 6, Oneplus 6T, Huawei P20 Pro, LG SJ810V TV, iMac late 2013. For example my Dell Vostro 5590 laptop is not affected at all, so as another PC with a TP-Link ac1300 wifi stick. I tried to switch off beamforming and fast roaming, switched to Google's DNS servers, but it did not make any difference. The only solution was that I created a guest wifi network with only 2.4 Ghz and connected the affected devices to it. So it is a workaround, but it is still not working as intended (I don't want another wifi guest network, and 2.4 Ghz is way slower than 5 Ghz), everything should work conentccted to my main wifi network without hiccups. These devices had no problem with past firmwares. Is there any news about a new firmware which solves this problem?
Thank you and I wish everbody a happy new year.
