I am sure you do. Depends what app you have. Mine is called WiFi Analyzer. But it doesn't matter what app you use, the fact is that the total channel width available in the 2.4GHz spectrum can only support so many devices, reasonably close, to maintain full bandwidth. The effect of adjacent chatter is simply to raise the noise level in your channel reducing the bit rate/range of your own kit.
That's the one I use, too. My problem is that carrier levels go up and down by 10dB while I'm just looking at the screen. That waht makes me think there's something I can see creating the problem.
Well that's just an artifact of sampling and traffic. Does the same here when wifi is being used
Really? Plenty for iPads.
You mean just another reason to avoid Apple?
If they're using Wifi repeaters, receive on one channel and relay on another? Probably blame the neighbours for crowing their spectrum too.
Yes indeed. One has to realise that no matter how powerful the signal from the router, its the device that connects to it that matters. If its got a weedy signal and there is a lot of interference then its not going to work due to the handshaking being disrupted by poor performance. I find it interesting, though that the next door bods turn off the wifi when they go home,, I guess it is safer from hackers and costs less electricity, but nonetheless, it might be worth a word with them as their router might be just the other side of the wall from your vulnerable device.

Different construction? Brick downstairs, plasterboard upstairs?
Many use 2.4GHz (either Bluetooth or a proprietary 2.4GHz thing), so quite possibly.

charles used his keyboard to write :
That up and down is perfectly normal, even when no other access points are around.
The Natural Philosopher laid this down on his screen :
13 individual channels, but wifi is spread spectrum, transmitting over three channels, the one selected, plus the two at either side of it.R D S used his keyboard to write :
Set up an old wifi router, connected to the first with a LAN cable as a repeater upstairs. Turn DHCP to off, on your upstairs router.
Could be, they operate on 2,4GHz as do wifi.
OK, that is a certain solution, but try adding an old router first.
Brian Gaff (Sofa) brought next idea :
If it is, then a sheet of bacofoil on the OP's side of the wall, at the back of the router will help reduce it.
It spreads a LOT farther than that. each 'channel' occupies about 6, in reality.
They are not quite that bad - at least for single channel use.
There is overspill into adjacent channels but the main problem is that to get the throughput the makers have been bonding channels together.
Mine is nominally 4 channels bonded but I have seen ones that bond 8 channels and that doesn't leave much room for anyone else!
I leave them at 20MHz on 2.4GHz, but use 80MHz on 5GHz
6 isn't a LOT more than the channel plus 2 each side.

It depends on how you interpret 'two at either side'
Again without punctuation that means a further two channels (one at either side)
Not a further two channels, two at each side..
And of course modulation being what it is, the concept of fitting in a channel or channels is not as exact as the words suggest.
Remembering the impact of aluminium foil faced insulation on wifi, maybe consider lining the wall at that end with even simple supermarket foil?
One that hasn't been mentioned is to use a slightly better quality of Wifi dongle with a high gain antenna. Morgan have quite a god one for not very much. I don't know if the new one is as good. The older ones were excellent for pushing the envelope with WIfi range.
Did you mean the cheaper (not in stock) version of this one? -
