To solve the problem I listed above, Sky asked me to do the following. Unfortunately, I can't find the way to access my router, is it in utilities or somewhere else? can you help?
a) Access the setup page for your router. This can be accessed by pointing your browser at 192.168.0.1 or the IP address listed in your routers manual.
b) Select the ADSL Settings Section.
c) Change Multiplexing Method to "LLC-BASED"
d) Select apply.
You’re On Demand connection should now work effectively. You should not require to restart the router.
Many thanks for your time.
The Sky on demand was finally resolved. Not thanks to Sky. The wireless connector (router) supplied by Sky is simply rubbish. Anyone considering on demand should not buy their connector. It simply does not work. They blame the supplier because they try to get you use Sky as your web supplier. Nothing to do with your supplier, nothing to do with your mac, simply has to do with their poor hardware.
The easiest and cheapest option is to use your home computer router directly plugged on the back of the Sky-box using ethernet cable. If like me, my home computer is two rooms aways from your TV, have the router wired to the sky box and use wireless for your home computer. Thanks to Mac quality equipment, no problem with the wireless connection on my home Imac.
My post is not really related to Mac forum, but if like me you are stuck and mislead by Sky, don't worry, nothing to do with Mac, all to do with Sky.
