Hi Good morning to you, what you need is to buy Wireless - G Linksys ADSL Home Gateway Model No. WAG200G. It come with built in modem. Once you install this wireless router with built in modem, You do not need Qtel Speedtouch Modem anymore. Just do the configuration with the new wireless router. If you want to buy just the wireless router without Built in Modem and intend to use Qtel modem, Im not prefer with that method, becoz not all wireless router are compatible or suitable with Qtel modem. So dont headache becoz just to safe few money. Buy with built in modem. Cheers mate
