Default 9.1-RC1 Wireless issues
Hi all --

I have a number of potentially related wireless/networking issues with 9.1-RC1 (amd64, Thinkpad X61, Intel 4965 AG/AGN wireless card).

Work maintains a campus-wide network named "ut-open". I can (generally) connect without any problems in my office. However, when I go to different buildings, I'm unable to connect to the same network name. Occasionally, I'll be able to
  1. delete the network profile ("ut-open"),
  2. Apply,
  3. wait for the network to restart,
  4. Add a network profile ("ut-open"),
  5. Check the Advanced tab for DCHP,
  6. Apply,
  7. wait for the network to restart,
and then maybe I'll have wireless. Is there a workaround for this?

A second issue is a driver crash when connecting to the wireless network in some of the other buildings. I've been pressed for time, but I'll try to sit down tomorrow and test this a bit more and see if it's as pernicious as it seems. See attached dmesg [1]. I've read a few other reports of this, but I don't recall a cause or solution.

Third -- I observed some weird behavior from lagg0 today. I switch between a wired connection and the wireless network so I have lagg0 enabled in PC-BSD Network Manager > Network Configuration (Advanced) tab. Since setting up 9.1-RC1 & using wired/wireless (w/lagg0 enabled) I haven't seen it in dmesg or in ifconfig. But it showed up this afternoon, after the driver crash I mention above. I've attached an ifconfig from shortly after the crash & the appearance of lagg0.

I'm sorry that this is so long. If a mod wants to break this out into separate threads please do so. My networking-fu is incredibly weak so all suggestions are greatly appreciated.

[1] dmesg -- sorry, it was heavily truncated for the forum post. let me know if there's a need to see all of it.

Confirming that the only way to connect to the same network, albeit in a different building, is to Configure wlan0 > "remove" ut-open > Scan > Add ut-open > Apply, with waiting for the intra-step network restarts.

Has anyone else run into this sort of thing? There isn't anything in wpa_supplicant (or something else) that caches the IP address in my office and then trys to apply it when I boot in another building?

Thanks in advance!

I have the Intel Wimax 6150 AGN PCI card on 9.1. Never successfully connected to my homes network yet. Card says associated but doesn't receive an IP address or anything.

earlier in the initial install days of 9.0, i used to have these nightmares. i could connect from home and not from office and vice versa if i redid the who issue in office. (at times, wi-fi would never get active and whatever workaround i did never woke that up)

i dont know if i am technically right but this workaround solved my issue.

i went for a fresh re-install, after first initialization of wi-fi network from network profiles, i clicked on restart network. next, i opened Network manager to see if wlan0 interface was listed. i hit the save button and then tried to reboot. this time wifi caught up.

similarly in any other networks all i had to do was configure wlan0 and add a new profile and save it.

perhaps you can create new profiles like Location 1, Location 2 etc ? i use the same service provider with auto DHCP but from different location. (Office and Home, in my case)

This workaround should work as the network will be activated on boot.
