Ive got a Toshiba Notebookwith Atheros AR9002WB-1NG wireless adapter. Generally it works fine, especiallywhen dhcp with various home based routers assign types of addresses /subnet masksin the range 192.xx with 255.255.255.0.in that case DNS and GWY settings are okand work.
However, when trying toaccess a free hotspot, even when signal is strong, it wants to assign addressesin the range 78.xx , and then, totally incorrect IP4 Addresses (in the range10.xx with similar prefixes for Gwy and dns servers ) and no IP6 are assigned; obviouslythe gateway is wrong and no DNS resolution can take place. By default the advanced parameter AdHoc 11nis disabled, in that case it doesnt even come up with the providers loginscreen. When I enable it, it does, but produces no further internetconnectivity, due to the above. I try to disable known automatic internet connectivity requests that come up prior to establishing a valid connection, but I doubt whether there's any relevance to my issue.
What grabs me is that asecond notebook, Dell Latitude with an Intel Pro WL 3945ABG is workingflawlessly in the same location on the same desk with that free public hotspot.
They differ in the set ofadvanced parameters (see below); I dont know whether this has to do anythingwith my problem. If it does, the Atheros driver version is 18.104.22.168, thesystem says it needs no update because the optimal version is alreadyinstalled, however their website has 10.0.0.52 versions for 64-bit machines,but I cannot force it to install after downloading and unzipping it.
802.11b preable is set to long and short
Network Address unavailable
Receive and Tx buffers (I toggle between 256 and 512, no effect)
Roaming policy (I increased to highest value)
Scan Valid Interval 60
WhereasIntels set specifies Wireless mode 6.802.11a/b/g
AdHoc default 0.802.11b/g
and CTS-to-self active.
Anysuggestion to help me resolve this issue? Thx a lot in advance, Thomas,Nice, France.
