Hi,
I have been having this really odd issue where connecting my wifi to 5Ghz wifi succeeds but then trying to ping or resolve an address (e.g. google.ca) will result in a “Host not found” error message. To get the connection to work I end up:
-
Set Network Manager to not connect to any wifi.
-
Then Connect to the 2.4 Ghz radio on the same card to the router (this always connects and gets internet access).
-
After I make sure I can go to an internet website or ping and address I will then connected using the 5 Ghz radio. I may have to switch between the radios till it eventually works. Sometimes rebooting the system and then the 5Ghz radio and network configuration allow and address to be resolved.
-
IPV6 is disabled, IPV4 looks like this:
- Both radios work 100% of the time if I use Windows 10.
Question:
- I want the “Intel Centrino Advanced-N 6205 [Taylor Peak]” to work dependably. Both my Thinkpads (x230 and T430s) use the same model of radio and have the same problem. Is this a known bug. Is there a fix?
Environment:
System: Host: hanna Kernel: 5.4.64-1-MANJARO x86_64 bits: 64 compiler: gcc v: 10.2.0
Desktop: GNOME 3.36.6 tk: GTK 3.24.23 wm: gnome-shell dm: GDM 3.36.3
Distro: Manjaro Linux
Network: Device-1: Intel Centrino Advanced-N 6205 [Taylor Peak] driver: iwlwifi v: kernel
port: efa0 bus ID: 03:00.0 chip ID: 8086:0085
Hi, i would advice to experiment a bit with the driver options:
$ modinfo iwlwifi
[...]
name: iwlwifi
[...]
parm: debug:debug output mask (uint)
parm: swcrypto:using crypto in software (default 0 [hardware]) (int)
parm: 11n_disable:disable 11n functionality, bitmap: 1: full, 2: disable agg TX, 4: disable agg RX, 8 enable agg TX (uint)
parm: amsdu_size:amsdu size 0: 12K for multi Rx queue devices, 2K for AX210 devices, 4K for other devices 1:4K 2:8K 3:12K 4: 2K (default 0) (int)
parm: fw_restart:restart firmware in case of error (default true) (bool)
parm: antenna_coupling:specify antenna coupling in dB (default: 0 dB) (int)
parm: nvm_file:NVM file name (charp)
parm: uapsd_disable:disable U-APSD functionality bitmap 1: BSS 2: P2P Client (default: 3) (uint)
parm: enable_ini:Enable debug INI TLV FW debug infrastructure (default: true (bool)
parm: bt_coex_active:enable wifi/bt co-exist (default: enable) (bool)
parm: led_mode:0=system default, 1=On(RF On)/Off(RF Off), 2=blinking, 3=Off (default: 0) (int)
parm: power_save:enable WiFi power management (default: disable) (bool)
parm: power_level:default power save level (range from 1 - 5, default: 1) (int)
parm: fw_monitor:firmware monitor - to debug FW (default: false - needs lots of memory) (bool)
parm: disable_11ac:Disable VHT capabilities (default: false) (bool)
parm: remove_when_gone:Remove dev from PCIe bus if it is deemed inaccessible (default: false) (bool)
parm: disable_11ax:Disable HE capabilities (default: false) (bool)
Here is a sample script to do so:
#!/bin/bash
# removes the driver module temporary
# and activates it with specific options
rmmod iwlwifi && \
modprobe iwlwifi \
11n_disable=1 \
disable_11ac=1 \
disable_11ax=1 \
power_save=0 \
swcrypto=1
Adjuste the values with written parameters. If something goes wrong… just reboot. The change is just temporary.
Beside that i would watch the journal meanwhile:
journalctl -f
