I work for a company & their internet keps dropping about 5 times a day.
It only started when a 2nd company with 10 new users began using their same dsl connection.
Rebooting the DSL P-660 Zyxel router always sorts it.
The router has wireless & looks after the DHCP.
There are also 2 other wireless networks which worked well before Company B arrived.
We have replaced the router & replaced the internal DSL wiring but it's
I checked it over the weekend & the router didnt drop but the office was empty.
It was permanently online so it must be an internal issue.
This morning as soon as the lads came in, it dropped again.
I'm thinking there could be a device flooding the network with requests?
There are all kinds of devices connected, windows pc's, laptops, phone's, ipads etc.
I keep getting this warning in the logs. It could be a clue?

I installed Wireshark on 1 of the windows pc's but not sure what to check for.
I could seperate the networks but Company B will be gone in a month.
