I have a Billion 7401VGP-R3. This supports 802.11g and 802.11b.
According to the wikipedia article on IEEE 802.11 the expected indoor range is 70m and 35m respectively. This should cover my house comfortably.
However, I am experiencing a useful range of around 10m on any device (various phones and a laptop). The internal walls are just wood/plaster and are not made of marble or anything.
Things I have tried so far:
- Upgraded the fireware on the Billion
- Checked the antenna is correctly screwed in
- Switched from Channel 1 to Channel 13
What else can I do to diagnose and fix this problem?
