Can close proximity to another router cause problems?

I live in a bungalow and use a spare bedroom as my office.
My router is in there with a windows laptop, a 2014 mini Mac and monitor.
I have had issues with internet cutting out intermittently for the last 2 years.
I have just found out that my next door neighbour is using his computer directly behind my wall.
Can the 2 routers cause interference with each other?

ADSL? FTTC? FTTP?

Ethernet? Wireless?

What about the neighbour?

What you suggest is a likely scenario if you are both running wireless. Or if the neighbour is wireless and you are ADSL or FTTC and not wired and filtered correctly.

FTTC, Ethernet to the computers and wireless to the smart tv (2)

is the internet cutting out to the two computers ?

if so, how is the router connected to the phone socket ?

Apologies,I have been away for a few weeks.
The internet cuts out to both pc, and the router goes into a new open reach phone socket. my phone goes into router.
I believe FTTC and my router is from sky.
The apps on tv`s plays up a lot ,with no internet outage

Plug the router into the test point behind the faceplate of the master socket, if the service still drops out then phone your ISP because you've ruled out everything that you are responsible for at that point.

I spent ages trying to get our Sony 55 TV to work via wifi. The Freeserve aerial was fine. Faced with choice of a 12m ethernet cable through the house from the router I bought a TPLink mains connector. Worked at once, no bother for last three years, FTTC at first, FTTP past year. Wifi is great when it works, but this old dinosaur has neither the patience nor knowhow to fiddle with it.

additional to jpm's comment, still use a microfilter do this........ see if drops connection. then try a spare, microfilter.

greysurfer225 do you know what type of master socket you have? has it one or two sockets?

Why? The microfilter should be straight through for FTTC.

Because microfilters can fail and the microfilter itself could be causing the problem.

That only helps isolate a fault down to a microfilter if you first establish that there is no problem when you try the test socket without a microfilter.

If you don't have a microfilter then you need to convert the RJ11 to a phone socket - not everyone has one of those sitting around but a lot of people probably have microfilters.

OK, fair enough, but the post in question was suggesting to try 2 filters as though they might be players in the problem.

i said try both because typically isps sends out two. Ian72 has explained perfectly why you microfilter a test socket.

Vdsl cutting out can be one of 5 things

a) intermittent line issues
b) router issues
c) microfilter issues
d) internal cabling issues
e) other applicances issues.

As you know doing a test via the test socket splits the issue mostly to a or b) and c). the easiest way to test further in this instance is to try a second microfilter - hence the double testing.

Sky will replace the router if it is thats what causing it. But Greysurfer would then be able to raise a fault knowning he's done a proper test and safe in no fees being applied to his account.

... hence the double testing ...

OK, thanks for this. So expressed in my logic: "You may need a microfilter to connect into the test filter. If this is the case, don't forget to repeat the test with another filter in order to eliminate the microfilter itself as the cause if there is still evidence of the fault"

This never crossed my mind because I threw away my dangly ADSL filters as soon as I got a faceplate filter and I don't think I ever had to use the test socket.

what is a test filter

I certainly didn't. I kept mine unused, i was asked by pn at one stage to test at the master socket test socket with the microfilter in. I had at one stage have a fault, and the OR guy junked my brought vdsl face plate and bunged a new one.

i didn't bat an eyelid - because i knew they were cheap and fail and its better to have a new one.

I don't care about this silly argument; what i do care though, is that graysurfer225 has had a second thread destroyed whilst asking for help and info

Eh? AFAICS, it is a reasonable discussion and relevant to OPs problem.
