Microwave oven interference?

[tvmaster2]

I have a TP-Link WR702N Wireless-N150 Nano Router getting power from (USB) and supplying the wireless network connection for one of my HD200 locations.

It's near the kitchen microwave, and from what I gather, when I fire up the oven, either the router or the HD200 is crashing.

Which would it likely be, and if it is the router (which is acting in a bridge mode I believe, piggybacking wirelessly from a nearby Netgear router) which is crashing, is there a way to have it avoid the microwave oven's frequencies (a Panasonic Genius)

Microwave ovens are known to cause interference with WiFi - especially if using 2.4GHz frequency (which is the only thing that 802.11b and 802.11g use). 802.11a uses 5Ghz. 802.11n and 802.11ac can use either 2.4 or 5GHz (some equipment supports both, but not all).

A lot of devices (especially things with motors - like vacuum cleaners) will also cause interference that gets transmitted through your power lines and can affect other equipment that way. You can sometimes attenuate that noise by adding ferrites to the power cords on the offending and/or affected devices (a lot of electronic devices already have these - if you see a small cylinder-shaped object on one end of your cord, that's what I'm talking about).

You could try switching from 2.4GHz to 5GHz for your WiFi network (may require a different router and / or different wifi adaptor for your extender). You could try configuring your router to use a different channel (within the 2.4GHz or 5GHz ranges, WiFi routers support several "channels"), but I don't know if it will help. You could try moving your router to a different location (or plugging it into a different electrical socket). You could try using a wired ethernet connection for Sage.

Before trying a bunch of stuff, you may want to do more to isolate / understand the problem... What is actually crashing (router or extender)? And what do you mean by crashing (do you just lose the signal temporarily? does it lock-up and require a reboot?)?

thanks - what seems to happen is any video playing back from that particular HD200 gets disrupted when the microwave is activated, resulting in a HD200 reboot - I believe the mini-router is being disrupted, which in turn locks-up the HD200

I have a touchscreen in teh kitchen running an HD300 (used to have a sage client running on a pc)... both get video stuttering when the microwave is in use. Music seems to be ok... internet is basically cut off. Something we just have to live with, I assumed.

Actually, I isolated the problem to ch's 1, 2, 6 & 11 on my Netgear router. I selected ch 8, as opposed to "auto", and the microwave problem seems to be gone.

You are basically just going to a high enough frequency that your particular installation is unaffected... microwaves introduce a set interference level and each application will be different depending on the quality of components and the placement of devices...

correct - and it's solved.
