So I recently got Vdsl installed which means a new modem. I have my TV & xbox plugged into my modem. When I plug in my laptop to the modem I get 26mbps down 10up, over wifi around 20 down 10 up. But over the course of the day the download speeds drop to around 3-5mbps over wifi. I turn off ALL other devices in the house (cordless phone, iPhone, turtle beach wireless headset etc) and I still get the same speed. So I then change channel on my modem to something else and it's fixed for a few hours then starts decreasing again. We primarily use or phones to do internet browsing, and pay a premium for better speeds, but cannot access these speeds over wifi. I know the speeds are there, but I'm losing so much over wifi.

Can anyone give me a suggestion on what I can do that does not involve plugging in my laptop.

To be completely honest you need to understand WiFi is a complementary solution to cabled Ethernet, it is not a replacement. 2.4Ghz WiFi in some urban environments is also becoming virtually unusable due to noise.

I could spend the next hour writing you an essay explaining why this happens and how to identify issues and resolve them, but none of it is going to be content that isn't already on the net. To be completely honest you'd be far better of using Google and researching much of this for yourself.

If 2.4Ghz is too noisy you may need to look at better quality equipment or moving to 5Ghz.

How many wifi networks in your immediate area that your devices can see?
Have you tried using a wifi scanner to see them all and see what channels they are using and then pick a channel that isnt used or has less 'traffic' on it.

I have a basic understanding of how wifi works and the different frequencys. That's why I isolated the problem to some sort of interference. There is around 3 other weak signals in my area. I change to what ever is appropriate. Thing is my turtle beach wireless headset uses 2.4ghz also, and after doing some research I find it runs on the higher channels. So I'mrerestricted to lower channels. But I still can't figure out why wifi is so abnormally slow when all the devices are turned off.

Where's your router located and is it up high or on a desk etc. As Biddle said.... There's a whole heap of crap transmitting on the 2.4ghz band these days. You haven't told us your set up yet I. E. Router type etcetera
