Or the extender plugs not connecting properly, which is more likely. Running a temporary Ethernet cable is the only way to prove it.
If the router is changed, then you would have to reset the extenders to default, and set them up again, as the IP subnet is most likely going to be different, so they will not pass data.
Yes, missed the mention of extenders.
Yes, I cannot imagine all those HH5s being faulty. Swapping between the HH5 and the TP Link, and then back again, would upset them.
I wonder which extenders are being used? If they are the BT ones, then this post explains how to reset them if they are not passing data.
I have always had a 500mtr Cu line to the Cab' so when the HH5 stats gave me 40Mb max data rate and 40Mb data rate (att' 29) I was confused.
I would do a speed test and the data rate was confirmed at 40Mb.
Wait a minute, what is the HH5 doing. Does distance & quality (Cu) not affect anything.
I don't know about electronics at all, but in hydraulic terms I would expect a pressure drop at the HH5 with predictable consequences.
In my opinion I have suffered those consequences.
Upon installing the N600 it gave me a max rate of 40Mb & 35Mb user rate. This in my opinion is about right.
The N600 has sat there for 35 days now without me having to do anything.
My Neighbours had many probs with HH5 and with a td 9980 zero probs.
They called to see me the other day just for a coffee and to ask if I would help eat the mince pies before they were past sell by date.
In others words a result!!!
B.T broadband fine Router a problem.
But we on this forum can see this all the time.
