I always thought the clip on idea was pretty poor and I wonder how many will get broken in due time.
Well I am not a fan of them, as for them breaking, its possible, but more likely to pop off first.
I got out my hot air tool and heated up the one on my desk to slightly soften the plastic on the side to persuade it out a little and then let it cool and harden back up.
Now mine is more firm but still able to be removed when the sides are pushed in.
Tonight’s latest offerings... 2 lines different providers same exchange cabinet.
Ouch, I know our two copper lines here when we had ADSL2+ on both of them, our main line was with Zen and got 6.5Mbps (no errors or dissconnects) and the second line was with BE at 6.8Mbps (had a few issues, but was stableish) then BE was brought by Sky which resulted in our speeds dropping to an unstable 5 to 6Mbps.
Then my brother moved out and took his Zen connection with him so we got BT put on our main connection, sadly BT would only give us between 4 and 5Mbps even though the line could handle 5.5 to 6.5Mbps.
TBH, we could never go back to ADSL2+ speeds
