Each night around 6:30 my internet signal drops off and is not usable at my house. We have a different set up because we live in a rural area. The cable company will come to the front of my property but not down our long driveway. So we have an old abandoned house we use to get the internet from the cable company. From there we shoot a signal to our house using a Nanostation. The Nanostation is attached to a router at our house that sends out the wireless signal. It works great during the day from about 7:00 am to 8:30 p.m and then it stops or slows to where it is not usable. I have contacted the contacted the cable company and they assured me that they are not seeing any loss of signal at that time to our modem at the abandoned house. Any ideas on why we can get internet at this time?

Is there anything else that starts up around this time.
Maybe automatic lights or heating..

This can depend on many things:

* As Curlyben mentioned, is there any other electronics that auto start during this time?

* Is there a circuit breaker near (under, next to, or above) the computer losing connection or near the modem/router/gateway? This usually would cause random connection loss, may not be timed as yours is but still something to look at.

* To elaborate on the auto-start issue: what time does dinner prep start in your household? A microwave, electric stove, bad light in the kitchen, etc could cause this and if you prepare meals at the same time every night, this is something to look at.

* Are you noticing you sit in a specific location at a certain time of the night where you are noticing this? If so, what room and what is around you. Please take note of any electrical sockets you are near at that time and what devices you turn on a regular basis.

Things to try when this happens:

* If it's a mobile device such as a laptop or tablet, walk around during this time and see where the signal falls off and where it is good. This can determine what may be causing it if it's interference.

* If there is another user in the household, see what they are doing during that time. If they take priority on the network, it may not be dropping connection completely, it may be giving it all to that user and kicking others off.

These are just some things that it could be that are easy to check. If it's only happening to one device, it could be a piece of software that is operating on the computer that has run in to a scheduled task. If it is the whole network, I would start looking more closely to the modem/router/gateway and the ISP.
