Details

I'm having trouble with all kinds of things in the Portland office: * DNS timeouts * 15-25% packet loss on pings to various hosts (European hosts, SCL3, Google) * Slow wireless initial connectivity (gets authenticated, and then drops multiple times before connecting) Just now: --- google.com ping statistics --- 169 packets transmitted, 152 received, 10% packet loss, time 168336ms rtt min/avg/max/mdev = 4.211/8.268/230.750/20.410 ms selena@taiping:~/repos/build/releng-private/passwords 10:49 ♥: Just prior to initiating this ping, i got DNS timeouts for twitter.com/facebook.com/google.com. Previous to that I got DNS timeouts looking up build.mozilla.org addresses, making it impossible to SSH into hosts and do my work. I'm connected via the VPN right now - maybe that's causing problems and dropping packets? I can't do my work though without being connected to the VPN.
My first guess is that you have a really bad wireless connection. Would it be possible for you to plug in with an ethernet cable, just as a test? Thanks

Hi! I had meetings all day today and could not plug into a wired connection. :/

This bug is rotting in my queue. How's life in the Portland office been for you as of late?

(In reply to Dave Curado :dcurado from comment #3) > This bug is rotting in my queue. > How's life in the Portland office been for you as of late? Unsure! Has anything changed? I still have a terrible time connecting to the wifi. Only in the office. Never at home/other offices/public wifi.
Flags: needinfo?(sdeckelmann)
ugh. Sorry. The original problem sounded like a WAN problem. But the issue is that you're having a difficult time connecting to the wireless network? So, let's see what we can figure out... are you up for helping me on this? - Does it matter where you are in the office when you try to connect? - Once you're connected, is your network performance OK? - Do you tend to stay connected or does the connection drop? - What OS and version are you using on your laptop? Thanks very much, Dave
I have been thinking about this, and there is a big difference between when you use the office wireless and when you use (probably) any other wireless connection: the authentication process. Everywhere else you're using the password associated with the wifi SSID. In the office, you're using a more complicated authentication scheme. Are you, by chance, using a mac? If so, have you seen this: https://mana.mozilla.org/wiki/display/SD/Mac+OSX+and+Wifi+Roaming Thanks, Dave

I am on Linux, but I wonder if something similar applies there? I can capture my logs for trying to connect to the 'Mozilla' SSID the next time I'm in the office. Maybe there's some kind of certificate issue. There's always a notice about the search paths being weird for DNS, also.

Yes, logs showing you attempting to join the wifi would be (hopefully) quite helpful. Thanks for your help and patience with this. Dave

Van volunteered to work with Selena on this. He's a better resource to deal with this than I am. (Thanks Van!)

spoke to :selenamarie, she's going to give the fix a try tomorrow and let me know how it goes.
the fix appears to have worked for her. will revisit bug on monday to see if she ran into any reoccuring issue. <van> are you still having wifi issues in the portland office? <selenamarie> yes <selenamarie> i made the change! so far so good. will keep an eye on it.
Van -- what is "the fix" ? THanks.

hiya dave, the fix was to delete the mozilla ssid and add the certificate back, instructions you provided in c#9.

spoke to selena this morning, she's still having issues. checked wlc logs and it looks like her laptop is choosing the 2.4ghz spectrum. she will let me know when she gets to her desk (after monthly meeting) for more in depth troubleshooting. - iwlan list scanning shows her laptop detects both spectrums. - reduced power on the b/g radios on her AP and cleared session, didn't work, AP put her on guest ssid. - had her move and cleared sessions, still didn't work - interestingly enough, it chose the same AP and still guest ssid. - asked her to turn off her wifi and turn it back on, it finally chose the closer AP and put her on corp.
:selenamarie, can you let me know the hardware model and o/s your laptop is using? sorry for the delay but we may have to use some work around since we're unable to pin point why your laptop isn't associating on the 5GHz spectrum.

:selena, this appears to be a driver issue as :decoder had the same issue on his linux x1 carbon. his fix was to disable network manager and install/configure wlcd although that probably will have it's own set of problems. do you want me to send you a small linux compatible USB dongle to test if you'll have better success with your laptop?

Yes! That would be nice.

:selena will you be in orlando? i'll bring the dongle and the drivers and we can test to see if it works for you.

hi :selena, any luck with the dongle?
