Question

microwave oven disrupts Wifi router's signal

by Sunniest / June 8, 2016 3:12 PM PDT

My problem is apparently common: When I run my microwave oven (a few feet away, on the other side of my bedroom's wall), I get thrown off the Internet. This problem was addressed on the forum in 2006....The poster was advised to (1) move either the router, microwave, or computer to a different location; or (2)"use a different wireless broadcast channel."
I'm not in a position to move anything around. I'm not very computer savvy: WHAT DOES "use a different wireless broadcast channel" MEAN?
Note: My router (in my apartment's living room) is an inexpensive TP-LINK (brand) 150Mbps wireless N router...based on 802.11n technology (the box says).
On the rear side it has 4 LAN ports and 1 WAN port. It works fine in my 1-bedroom apt. (except for the microwave disruption). My computer is a Mac Mini.
If I need to buy a fancier router, I will (if it's not expensive).

Try rolling it back to 802.11g and changing the channel.

Your microwave is 500 or more Watts
by R. Proffitt Forum moderator / June 8, 2016 3:33 PM PDT

And the tiniest of leaks will wipe out 2.4GHz WiFi.

Either take the prior advice or move to a 5GHz router and adapters.

Wireless headphones interrutping WiFi
by Chocomaria / June 9, 2016 3:19 AM PDT

Question to R.Proffitt and others:

My roomy is using wireless headphones (from Sennheiser I believe) that keep interrupting the WiFi connection. Apparently it's running on 2.4GHz, which is the same as the router setting I'm told. Even though the connection is showing full bar, pages while surfing or videos streaming won't load properly making it quite annoying. She's tried to follow product instructions but it doesn't seem to help. Is there no other choice but to invest in a 5GHz router? Will that solve the problem completely?

Thanks for any advice on the matter Happy

There are other choices.

Get wired. It's immune to such issues.

Headphone manufacturer with a suggestion
by Chocomaria / June 10, 2016 5:29 AM PDT

Thank you very much for the response, R. Proffitt.

Yeah, wired would be the best solution and a friend suggested to perhaps invest in a so called powerline adapter. Only issue would be that our cell phones would need to connenct wirelessly.

I did found a guide on the headphone manufacturer's homepage that suggests to switch off the router for 15 minutes so that the headphones have established its signal first. Then after 15 minutes turn the router on and have it "find" a different bandwidth that won't be affected by the headphones.

If this doesn't work then I guess the 5GHz router or a powerline adapter would be the best path.

That can help.

Newer routers automatically find the open channels but microwave ovens have been trouble for WiFi for years. I can't know if your oven is old or leaky but usually it's an older model that has seen better days.

Footage shows the issue
by Chocomaria / June 9, 2016 6:37 AM PDT

Hi Sunniest,

While looking for an answer to my own question further down I saw this YouTube video where someone is showing how the microwave is affecting the WiFi signal.

2.4ghz signal interference Wi-Fi due to Microwave:


The video seems to be a little old but he too recommends to buying a router that also supports 5GHz.

I am experiencing the same issue as the video is showing, but rather due to a wireless headphone. We have a printer that also connects to the same WiFi network. Hopefully the printer and all my other devices support 5GHz if buying a new router is the only solution.
