I have had broadband from Madasafish (and previously freenetname) and telephone from BT since forever, but was getting increasingly disillusioned by paying as much as £14.99 per month for a meagre 5GB of broadband. I was a bit apprehensive about moving, not least because I wanted to retain my domain name and webspace inherited from freenetname days.
I eventually decided PlusNet was the best bet because (a) as a sister company to Madasafish, they were able to reassure me about the retention of my domain/webspace, (b) the deal was OK, but only if I moved my landline as well (I'm on a Market 1 exchange so the numbers aren't nearly as attractive as the promotional material would have you believe), and (c) I found that by signing up via a link from moneysavingexpert.com I was promised a £50.00 cashback from PlusNet.
Well, the migration is now complete, and I have to say it went remarkably smoothly, and all according to the timetable promised by PlusNet. I've seen quite a lot of negative press about the Technicolor router, but so far I've been impressed. I've moved from a Netgear DG834 non-wireless, and have seen a slight increase in download speed (from approximately 5.1 Mbps to perhaps 5.4 Mbps). I had a wireless card on my desktop, configured as peer-to-peer, so although I could talk from my laptop to my desktop and vice versa, I couldn't add in anything else. Now with the Technicolor's access point, I have added in my HTC Hero smartphone, my Canon MP620 printer (previously wired to the desktop) and my A C Ryan PlayOn!DVRHD TV recorder.
The only downside so far is that the retention of my domain and webspace is only achieved via a kludge: keep the Madasafish account open, but downgraded to "Justmail", at an unbudgeted cost to me of £1.69 per month. Granted it seems to work OK, but the method of achieving it seems to me inelegant.
I have yet to see (a) my £50.00 cashback (I'm led to believe it'll take about six weeks), (b) my final bill from BT and (c) my next bill from Madasafish. I'm keeping my fingers crossed!
