What can I do to improve the wireless range between my Vodafone modem and my

computers?

Wireless modem/routers use a frequency spectrum that is shared with many other wireless electronic

devices such as other wireless networks, video senders or microwave ovens. Although the modems are

designed to cope with a certain level of interference, in some environments it can be difficult to

achieve optimal performance.

There are several measures you can take to minimise interference and improve the range between

your wireless modem and computers.

1. Most wireless problems are due to interference from other network or appliances. You can change the

wireless channel used by your modem to try and avoid those interferences. Start by trying channels 1, 6 or

11, then try all channels in between if necessary. Wait for 60 seconds each time after changing the channel

to verify if the signal has improved. As all environments are different, there is no easy method for doing this

other than trial and error.

2. Position the antenna vertically on your wireless adapter (ignore this step if you use an Apple computer with

a built-in wireless network adapter).

3. Locate the modem in a central place in the house (where telephone socket allows).

4. Locate the wireless modem over or on your desk/table, not under it.

5. If the wireless modem is on the ground floor and range is a problem upstairs, try positioning it on a shelf.

6. Where available on the wireless adapter, use cables or antenna extension provided to locate wireless adapter

away from your computer and other sources of interference. Ignore this step if you use an Apple computer

with a built-in wireless network adapter.

7. Move all wireless devices away from potential sources of interference such as microwave ovens, metal

sheets, cordless phones, cordless keyboards and mice, video senders, etc. Switch them off or move them

away to identify which one interferes. Some devices such as video senders offer the possibility to change

their channel of operation so if possible try configuring an alternative channel on the other devices too.

8. Interference might be intermittent (for example, if a video sender is only used in the evening, or when a

microwave oven is being used). Therefore you might need to check for electrical devices that are only used

at certain times.

9. Some laptops with a built-in wireless adapter will provide lower wireless performance than an external

wireless adapter such as a USB dongle. Consider upgrading to a USB wireless adapter or borrowing one for

testing where possible.

Back to the Start.
