The short answer is distance from the hub or router, wireless standard used and interference from other devices. There are so many factors which can affect your wireless that it's almost impossible to cover all of them. We'll cover most of the major ones below:
- Distance - Obviously the further your device is from the wireless access point (usually your hub) the weaker the signal.
- Wireless standard - If you're using the BT Business Hub 3 with 802.11n wireless your wireless range is roughly twice that of the BT Business Hub 2 with 5x the speed.
- Electrical interference - If your hub or router is next to another electrical device such as a computer or microwave this can interfere with your wireless.
- Other wireless networks - If you're in a town or city there may be lots of other people around you with wireless networks on the same frequency as you. If you're using the BT Business Hub 3 it'll automatically choose the least crowded of the 11 available wireless frequencies.
- Nice thick walls - If your building is really solidly built this can degrade your wireless signal if it needs to pass between walls.
Often most of the above can be fixed by repositioning your router a bit. Keep in mind you shouldn't move it from the master phone socket on your line as that may degrade your overall broadband speed.
Fortunately there's also some nice new tech called HomePlugs (also known as Powerline Ethernet) than can help you expand your wireless network. You'll find many options available at
BT Business Direct.
