When I answer my cordless phone, I get knocked off the internet on
my wireless connection. What can I do to resolve this problem?
This is a problem that many people are unaware of, but happens quite
often: household wireless phones and computer wireless (WiFi)
connections can come into conflict.
There are a couple of solutions.
To be clear, I’m not talking about cellular or mobile phones. The issue here is caused by more traditional cordless land-line phones.
These phones typically operate on one of three frequency bands:
As I understand it, the higher frequency bands typically offer longer range and improved quality over the lower.
By now you might guess where this is headed.
802.11b, the most common WiFi protocol, also uses the 2.4 gigahertz band. And 802.11a, currently less common, sits in the 5 gigahertz band.
There are two solutions: one simple, one free.
Simple: buy a new phone, making sure it’s not using the frequency range that’s used by your WiFi connections. My guess is that you’re probably using 802.11b, since it’s most common, so simply get a 900Mhz, or a 5Ghz phone and you should be set. Give your old phone to a friend who’s not using WiFi.
Free: move your WiFi equipment away from your phone. How far away depends on everything from the specific equipment and phones involved to the layout of your home or office. But if you can, for example, swap your cordless phone with a different phone further away in the house, that might be a start. Or if you can move both your access point / router and your laptop away from the cordless phone, that might also help. As you can see this approach, while cheap, will require a little bit of trial and error to see what works in your situation.
