We have been having serious problems with our BT Infinity connection. Our Smarthub thinks it is properly connected to the BT network, and our devices can connect to the Smarthub via WiFi, but we frequently get no Internet connection. This can (usually) be fixed by resetting the hub, or switching to another hub, but the problems come back.
We have tried a variety of solutions, including a BT engineer visit who found no problem, and a replacement Smarthub.
I have discovered that the Smarthub event log is very busy, with many requests, failed DNS connections, and other events that I do not understand (see attached snapshot -- this type of activity is constant, with an event every few seconds). It looks to me like there could be some kind of malware at work here.
At the time of this snapshot below, there were two devices on the network:
There are two kinds of event in the log that appear most often (both in snapshot below):
My current theory is that hub is timing out device connections after the numerous DNS name resolution failures. Is this possible? Can anyone comment on that theory, and whether the activity shown in the attached log is normal?
Thank you for the replies. I will try to avoid restarting the hub, but what should I do for the hours on end when the hub says it has a good connection, and our devices will connnect to it, but we get no Internet connection? The BT engineer who came out seemed mystified by this. He ended up fixing it by making about 4 calls to various people at BT, and then doing a hard reboot of the hub. But this only fixed the problem for a few days.
Just to confirm, a few more things from the event log, after I just arrived home.
If all this is normal, what should I do next to try to get a reliably working Internet connection -- besides not restarting the hub, since the problem arises without me restarting the hub?
Maybe try entering static wifi settings on your iPhone to see if it stays connected. I have done this with my iPad.
