When my exchange was upgraded to 21CN this year I saw an increase in connection speed but also a couple of loss of PPP session daily. Eventually I got Plusnet to switch on interleaving which then immediately gave me a 100% stable line.
Then last week I decided that I would take advantage of faster uploads and got Plusnet to uncap my upload speed, it went up from 446 to 864. They told me that this would not have any effect on my download speed, which it hasn't. But I am now getting random disconnects a couple of times a day.
It looks as though interleaving is still on and I have asked Plusnet to confirm this to me
My question is does uncapping the upload speed have any known effect on download or line stability ?
