[opensuse] Wireless connection issue
Hi all, I travel a lot for my work, and I've noticed many times that Linux wireless networking often doesn't connect to the networks that I'm offered in hotels. I'm pretty sure (call me cynical, but...) that this is an issue with micro$oft base stations that expect a little bit of non-standard protocol. Since windoze adopts (creates?) that protocol, it all works for them, so nobody recognizes a problem. Part of the reason I believe this is that I've found that if I reboot my machine into windoze it will almost always connect successfully. (Such is the case today, this mail is being sent from firefox under windoze, yuch!) Sometimes, but not this time, I find that if I've first connected using windoze, I can then reboot back into Linux and the network connects properly (suggesting that the protocol issues are something to do with a one-time recognition of the machine's MAC address. Anyway, is this something the SuSE community knows about, and maybe has a workaround for? If not, can I do anything to provide packet traces of windows succeeding and of Linux failing to connect? I used to use ethereal but that doesn't seem to be part of the distro any more. Is there something else I should use? And either way, what would be a workable tool under windoze?

Does Microsoft make WiFi base stations, as would be used in a business? Actually, I'd suspect the problem lies with the authentication server, where you have to log in to get to the internet. It's entirely possible that it is using something that's available in IE or Windows. I have never experienced such an issue anywhere I've used my computers, such as coffee shops, the library etc. Is your problem that you can't get a WiFi connection? Or you can't get beyond authentication? -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Hi, I was able to suss this problem out a year or so ago. The problem is a TCP window scaling which Opensuse doesn't address. To be able to connect, open console and type in as root the following, then enter: /etc/rc.local echo 0 > /proc/sys/net/ipv4/tcp_window_scaling then you should be able to connect, and when you shutdown your laptop and restart, do it again. I have had this mostly on wireless routers in hotels, but I had it once on a cable ethernet connection as well. There is more info about this at: http://wiki.archlinux.org/indes.php/Configuring_network#How_To_Diagnose_The_... If you have the problem with windows vista, you may read of the solution here: http://support.microsoft.com/kb/935400 Hope this helps.

Hi, I see that my links are broken, but here is a fresh one that will give you some info: http://wiki.archlinux.org/index.php/Configuring_network The bash command works well, just the links with info are old and don't take you where you want to go to learn.

It looks like the command is just a little shorter than what I gave previously, it may be just the way that I have written it in the little notebook that I carry.

I have no rc.local on my 11.0 system, but the rest of the command works--"echo 0 > /proc/sys/net/ipv4/tcp_window_scaling." Thanks for the hint. Ed -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

The fast fix that I found was to use IE4Linux, after connecting to the base with that, I am able to use FireFox. I do complain to the Hotels, and tell them that not everyone wastes money on Windows. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I travel a lot. I sometimes encounter the same problem (windows only, expensive 1 hour internet...) at hotels in Denmark. I check this BEFORE I book, however. Then I call them up and tell them that they've just been deselected. Quite a few hotels have granted me free unlimited internet access uppon that message. The others have not received my visit. -- -------------------------------------------- Med venlig hilsen/best regards Verner Kjærsgaard Novell Certified Linux Professional 10035701 www.os-academy.dk +45 56964223 -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
