Cleaning supply to a WIFI antenna

[pgrbff]

I have recently installed wireless ADSL, the phone company dont offer ADSL and the satellite ADSL system I was using is too expensive and the latency was a problem.
The antenna keeps resetting, up to 30 times a day, and the suggestion is that voltage fluctuations are the problem. I do have a terrible supply, the lights, and the bathroom fan change every time you switch on an appliance elsewhere in the house.
Is there any way of stabilising the voltage?

You could stabilise the supply to the antenna/modem with an "online UPS". Check the antenna's power requirements, which i imagine is modest, and you may be able to find a low power 'online UPS' that is reasonably priced.
Perhaps your incoming supply cable is not up to the job!

It isn't up to the job, they have already changed it to max 70mm(2) So I'm stuck with it, and I only have a 5kw supply. I thought of a UPS but wasn't sure how they worked and if they would actually even out the fluctuations.
is an "online UPS" different from a std UPS?

Yes. Crudely, a normal UPS directly outputs the mains supply that its connected to until there's a failure and then switches to the battery inverter, and there may be a 'brown-out' or a bit of a messy output during the switchover. An 'online' UPS permanently charges the battery which powers the inverter, and the inverter permanently supplies the output of the UPS, so you get a genuinely un-interrupted output waveform whatever the mains input is doing.
There are good one's and bad one's and I have no experience of this market! Some output a nice pure sine wave, which is probably what you need, and some more of a square wave which might interfere or upset what you connect to it.
Hopefully someone may be able to advise.
Otherwise try Googling spec's and reviews etc.
Good luck!

I may be wrong, but I think that link is for the battery pack for the UPS, not the UPS itself, although it does read as if it's the whole thing. The part number seems to be that for the battery?

I was thinking an altogether lower power unit (and hence less costly!) might do, if such a thing exists.

I am not sure that varying mains voltage is the problem. Check the power adaptor and see what voltage input range it accepts; most likely it will be globally compatible which means it will work right down to 100V or less. There is no reason why your voltage should drop so low unless there is actually a broken connection, and many other appliances and lights will stop working before that point. Can you run it from another source to prove the point, or connect something else that will give a reasonable indication of the voltage at the outlet where the WiFi AP is plugged in? Obviously if you actually have a wiring fault that is causing the supply to drop out entirely that is also an electrical hazard as it might be arcing.

Historically (1970s and before) it was true that computer equipment was voltage sensitive, but now most computers and accessories are pretty robust against power fluctuations. I routinely run racks of studio equipment on portable generators without incident - the UPS is only needed to keep it all going while the generator is being moved or refuelled.

Or a voltage Stabiliser

Is the voltage fluctuation only in your property or do your neighbours suffer from it also?
