I just had a guy out to fix my internet, it kept going out, especially in the late afternoon. He ran some tests and said that the return signal was too high (it’s supposed to be around 46, and it was 59.) That’s what was causing the router to fail. Apparently the heat will exacerbate the problem, because he said this mostly happens during the summer during the hottest part of the day.
In: Technology
* Data signals, like those used in broadband internet connections, use electrical voltage to transmit data.
* If the voltage level is too high going into a receiver, it can overwhelm it and cause false readings.
* Most communication systems have the ability to have bad data resent, but that slows things down as it takes longer for the data to get from A to B if a large enough percentage of it needs to be re-sent.
* At very high speeds, small changes in the cable’s properties, (like heat) can start to have a bigger impact.
* It’s possible the level of the return signal was already high, but not too high to cause major problems.
* However on a very hot data, that might effect the cable just enough to cause the return level to be too much for the receiver.
