In fact they are shit.
Trust TP Link router finally gave up the ghost - predictably at the most inconvenient moment. Have a replacement due tomorrow.
As a stop gap, I figured I could switch my VM so-called "Super" hub oput of modem mode and use it to replace the WiFi my router was running seamlessly so SWMBO didn't notice.
Only when you do use the POS as a router, it won't allow passwords with spaces in (which my router did). So I had to intervene to set SWMBO up again.
Just in case you were wondering (1) it doesn't tell you you can't use spaces - but that your password needs to be >10 characters (yes), contain
1 upper case (yes) 1 lower case (yes) and one number (yes).Rant over.
