1.1Meg as in 1.1 Mega bits per second reported by what? A speedtest such as our own, or the pop-up icon saying at what speed the wireless card is connected?
The 824M is fairly old, and it may be the 802.11b card you are using is also old, and they just don't work that well together.
802.11b should manage connections of 11Mbps when in the same average sized room, giving a maximum speedtest of around 4 to 5Mbps.
802.11g, will connect at 54Mbps in that case, and speed tests of 15-23Mbps should be possible. Assuming the broadband connection will feed data fast enough into the property.
