khink, did this problem not occur in a release prior to Raring? ** Description changed:
- 802.11n networks don't show up in the network manager. + On my Lenovo Thinkpad Edge S430 802.11n networks don't show up in the + network manager. With N-band enabled, i see a lot of "Tx excessive retries". WORKAROUND: Disable N-band explicitly in /etc/modprobe.d/iwlwifi.conf. + + 3) Regarding your wireless Access Point (AP): A) What is the AP manufacturer, model, and firmware version? Mikrotik OmniTik UPA 5hnd + B) What wireless connection type are you using (e.g. 802.11n, 802.11g, etc.)? Only 802.11n has a problem. + C) Encryption Type (ex. WEP, WPA2-PSK TKIP/AES)? WPA2 + D) MAC Filtering: None, anyone with password can connect. + E) QoS/WMM Don't know - what is it, how do i find it? + F) Beacon Interval Don't know - what is it, how do i find it? + G) Router Internal Firewall Disabled. + a) If you change any of the settings above does it change anything? Haven't tried and i'm not at liberty to do so. + 4) Does another wireless device tested with the AP have the same problem as the hardware you initially reported with? Not to my knowledge. + 5) What is the distance of the wireless device from AP? About 5m. + 6) What is the number and type of obstructions between your device and the AP? One door. + A) If you bring the device close to the AP and eliminate obstructions, does this change anything? No. + 7) Does the issue occur with different APs? Yes. I first noticed it at the workplace, which the data in this comment is for, but recently when i was at a conference, i noticed other people could "see" an N-band network while i couldn't. + 8) Is it a regression (e.g. did the problem happen in a prior Ubuntu release)? I don't know that. + If so, what release specifically did it last work with? + If you do not know, could you please test for this in the earliest release of Ubuntu that is supported as per Ubuntu Releases? <MISSING> + 9) Does this problem occur in the newest mainline kernel following https://wiki.ubuntu.com/Kernel/MainlineBuilds? Please mention what specific version of the mainline kernel you tested with in your report. Latest tested is v3.12-rc4, while latest available is 3.12-rc7. + If the mainline works, does the Ubuntu provided stable compat-wireless backport work following https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-wireless_in_Ubuntu? Please mention in your report the specific version you tested. + If the mainline does not work, could you please test upstream's compat-wireless backport via https://wiki.ubuntu.com/Kernel/LinuxWireless#Compat-wireless_from_upstream? Please mention in your report the specific version you tested. <MISSING> + 10) Does ndiswrapper work following https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper?
