Recently, I had reason to turn off my ADSL modem - a Thompson SpeedTouch585i - yes, its wireless.
Since then, I have had nothing but troubles trying to connect my laptop back to the internet via this particular modem. (Edit: I havent got a spare modem
I am running edgy on a pentium III laptop, using a D-Link wireless card. (Edit: I think its worth pointing out here that it doesnt matter if I go wireless, or via ethernet, I get the same result)
The network connection is good, as I can browse the modem's user interface, and establish telnet sessions to the modem, I can ping the modem, and also anything else connected to the network, but cant ping my WAN IP address, the WAN IP address's gateway, or even good ole' 18.104.22.168 (google.com.au ip address)
I know it isnt the internet service itself, as it shows up in the radius logs, and shows as being connected at the ISP's end, Plus, my main PC (where I am typing this from) is able to get connected wirelessly through the same modem on both Ubuntu and Windows.
I had a thought that it may have had something ot do with iptables, so, I flushed them all, not that there was anything there anyway, and I also uninstalled the firewall I had installed on the box.
None of this seems to have brought about any connectivity back to my laptop.
I have had this problem once before, and because there was practically nothing on the laptop, I just reinstalled Ubuntu, however, this time around, this option is an option of last resort, as I have a few important files and emails on there that need keeping!
One more thing before I leave you guys alone......I mentioned that when I try to ping the WAN IP address, I get nothing. When i try to traceroute to 22.214.171.124, the trace dies just after the WAN IP. Could this be somthing to do with the way the packets are being sent?
I swear to god I have not touched anything in the way of networking for over 6 months now.
Can anyone suggest anything that may either get me going again, OR at least point me in the right direction?
If you require any information from the laptop, please let me know and I can get it for you.
