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
