Re: [ubuntu-uk] some user losing internet access
For anyone interested, the problem with some user getting online and others not, after a lot of hacking and telewest (hiring a BT adsl line) swearing that it was nothing to do with them or there equipment and that we should use windows etc, turned out to be a faulty in line filter (provided by telewest/BT) on the line. I am not happy in some respects, and extremely happy in others. How could I doubt the ubuntu systems...?

Also you can try 'tail /var/log/messages' and 'tail /var/log/syslog' for more info. One of these may tell you what just failed and caused the network connection to drop out. -Gav -- ubuntu-uk@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-uk https://wiki.kubuntu.org/UKTeam/
Re: [ubuntu-uk] some user losing internet access
nice thought, but there's no firewalls installed :(. I'm at a bit of a loss... it's basically a pretty standard install. the only extras are ssh and fail2ban, but neither of those should effect connections (that I'm aware of). looks like I'm gonna ave to re-install :( time and messages appreciated.

Re: [ubuntu-uk] some user losing internet access
well... thats quite a comprehensive answer! Thank you, Chris. ok: the machines with the problems are both hard wired. wireless has no problems at all with the internet, and so I'm assuming have no relevence to the hard wired machine's intermittant connection. admin accounts have no internet interuption. only user accounts, so Im assuming it's software in the OS itself. the wireless machines are customers, so I couldn't tell you the hardware they are using, but as I said - they have no problems :/ the box's in question are used in cafe's around bristol. there are six, all in different places, but only two have problems (that I know of). and yes - I am using network manager in gnome to connect automatically. Given all this (and the reason for my confusion with the problem), 1> can't be hardware/drivers because the admin account runs ok. 2> interference? i'm not using wireless - and anyways the admin account stays connected ok 3> not wireless managers (not wireless) which leaves me with software. what could give a an intermeittant conection on a hard eth cable line for only some users (non admin ones)? sorry - hope this is clearer than the last mail and that you understand my problem a bit more - i need to practice making these things clearer - but I'm getting better (i hope)!

How many computers have you got connected to the wireless access point - Is this an internet cafe type setup, or a couple of computers set up for staff? What kind of wireless card are you using in the PCs? If you run the command 'sudo lshw -C network' - and post the output here it should tell us. Are there other wireless access points in the area? If so, are they on a similar channel - they could be interfering. Running 'sudo iwconfig' will tell you which interface you're running wireless on, and then running 'sudo iwlist scan' will show other access points in the area. What are you using to connect to the network, network manager? So in summary: 1> Problems with hardware/drivers 2> Problems with interference 3> Problems with software/wireless managers Other than that, try posting your issue at https://answers.launchpad.net/ubuntu/ too - it's worth getting help there too.
