Just moved house and got a TelstraClear cable broadband connection and got problems with the router I had.
(F5D8233-4v3(01)
Entered the supplied static IP etc into the Belkin N Wireless Router and.... No internet connection - the internet LED flashes yellow.
weird. the laptop got online ok with the same IP settings directly wired to the cable modem...
a search online about it found on Belkin's own website, this exact problem. (http://www.belkin.com/au/support/article/?lid=ena&pid=F5D8233au4&aid=10186&scid=0)
Essentially they admit a bug in the firmware prevents a stable (or any) connection to TC cable.
They supply a "beta" firmware update (at the link above)
I updated the firmware using this special firmware download but still no joy.
I also tried the latest general release firmware for this router- no dice.
looked through geekzone's forum advice - "stay clear of belkin for telstra clear" - not a nice answer!
but it was mentioned that the LAN IP of 192.168.1.x might cause problems.
mine was by default 192.168.2.x so I thought " not an issue". wrong.
after other troubleshooting I changed the LAN IP to 10.0.1.1 and suddenly as if nothing had ever been wrong, I got a live connection.
so there it is, if you have telstra cable, and your belkin router just WON'T work. try changing the LAN IP. It makes no sense whatsoever but it worked for me.
hope this helps someone.
