Hello, My specs: ========= Wireless Access Point: ---------------------- TP-LINK AC1200 rev1.2 PC1 (my laptop) --- - Lenovo Thinkpad X250 - 03:00.0 Network controller: Intel Corporation Wireless 7265 (rev 59) - Arch Linux (4.6.0-rc6-mainline, I need to update) - Confirm the bug under 4.5 PC2 (brother's laptop) --- Acer subnotebook Intel 7250 (iirc) Ubuntu 14.04 stock kernel PC3 (htpc) --- Zotac HTPC (BI323) 01:00.0 Network controller: Intel Corporation Wireless 3160 (rev 83) Fedora 23 64 bit with boot-to-Kodi Newly Ordered PC (cannot confirm yet, could possibly test windows): ---------------- Lenovo Thinkpad T450 Intel 7/8250? Don't know yet, but I know it's Intel again. Will run Ubuntu 16.04 or 14.04. Not sure yet They all have in common: ======================== - Linux, Intel wifi card and TP-LINK Archer AC router AC1200 rev 1.2. The problem(s?): ================ When near the TP-LINK access point, NetworkManager needs reconfirmation of password. On the htpc, this means loggin in on the console, `nmtui`, activate connection. On the computers with DE, this means a dialog box opens asking for a password, which is already filed. Pressing enter connects to the network. My laptop, as my brother's, tend to lose the connection now and then. When I checked `dmesg`, it said to be "lowering the transmission power as requested by the accesspoint by -xdB" (not those exact words, I can retrigger the exact error though), before losing the connection some seconds later. Other tested (working) configurations: - TP-LINK Archer C2 (which is without AC iirc) - Good ol' Linksys WRT - eduroam at my uni - any other wifi point I've ever had access to. - Tested another PC with a lot older (Intel) WiFi card (with AC): same issue. Not tested: - Windows (don't have any Windows pc with those cards near me atm) I see two options here: - TP-LINK bug - Intel iwlwifi bug Please advice on what I should test, which logs to send, ... Thank you for reading this WOT! Ruben De Smet
