Use channel 1, 6 or 11.
Plenty of computers sold in the UK even on windows can't find channels 12 and 13
I pretty much guarantee this is the problem.
You say other channels cause drop outs. I highly disbelieve that. Most routers use 1 6 or 11. This avoids overlapping channels.
So if 6 causes drop outs chances are 11 does not.
Also by using 13 you are interfering with routers on channel 11 due to overlapping channels.
So being on 13 you are still getting interference from routers on channel 11
You'd be better on 11 than 13 if there are devices using 11. Why?
When two routers are on the same channel they work together.
Eg router 1 transfers data, router 2 holds off for a micro second before transmitting.
This means that routers 1 and 2 don't collide with each other wirelessly.
On channel 13 with your router and channel 11 on another router...
Router 1 (ch 13) can't see router 2 (ch11)
Router 1 and 2 both transmit data wirelessly at the same time pretending each other don't exist
Net result is collisions in the air which means the data has to be sent over and over and over and over before it finally gets to you
Net result = performance degradation compared to sharing the wifi channel where both can work together.
On the same channel they wait for each other avoiding collisions completely. This dramatically reduces the need to constantly retransmit data. It's better.
The IDEAL solution is to have 1,6 or 11 with no other router on. So it's all yours.
Lesson use 1 6 or 11.
