Problem description
----------------------------------------------------------------------
When i transfer data over wifi i see my ping times go up and after a couple of pings i cannot transfer data anymore.
when the copy file action will be stoped and the wireless will come back and when i don't stop de file copy than my pings will sometimes reply but most of the times i do not get any reply
The SSID will still be send to the notebooks but there is not data connection available anymore on only this notebook.
Other notebooks will still be able to go to the internet and download some files but when i start copying a file from another notebook also that computer will be down after a couple of seconds
Tested this also on a wired computer here we have no problems.
Downloaded a 100 and 1000mb test file from http://ftp.snt.utwente.nl/pub/test to the local harddisk of the computers is was very slow but the connection was not interupted. speed on wifi 156kB/sec
Same file on wired around 500kB/sec
Testcase:
----------------------------------------------------------------------
copy a .ISO file from my notebook to a server in the internal lan. around 700mb
copied a movie file from around 5mb
Downloaded file from internet 100mb and 1000mb multiple times
Logging and troubleshooting
-----------------------------------------------------------------------
i did not found any logging with errors or other stuff in it.
When i start a tcpdump on the interal interface i see that the data directly stops from that notebook
when i start a tcpdump on the Wifi interface i see that when the data transfer will be interupted the notebook only does an arp request
Access to the firewall
--------------------------------------------------------------------
If someone would like to get access to the firewall please ask me i will create access to the firewall for you.
i hope this helps you to investigate the problem
