Made up with o2 customer service
Basically, what had been happening since the changeover, was randomly, every now and again, the connection would drop out and take a few seconds to reconnect. It happened every few hour's, but at peak time's it did happen a bit more regular.
At first I thought oh well it will be the migration, as the connections do tend to need a few days to "train" to the line etc.. So I gave it over the weekend, but it was still doing it on Monday night.
So I decided to telephone customer services, especially as it was free.
Phoned them at about 18:30ish, had to wait in a queue, but only for about 15 seconds or so. Got through to an British Paskistani/Indian chap (could tell he was British as he did have a tinge of a Scottish accent, and spoke both clear and fluent English, not like the foreign call centre staff you get). He was very helpful, asked the security details etc, and then asked to explain the problem I was having and to take my time if nessecary (it's a free call, so this doesnt make them money).
Anyway, after listening to my explanation, he asked me a few further questions, and then advised me what he believed to be the problem and explained clearly what it is, what he would be doing to fix it etc... He seemed to be trained very well, knew what he was doing and was very clear.
He advised me that it was likely to be the noise tolerance on the line and that he could fix this by increasing the tolerance slightly, and I would see the router reboot itself any second. Sure enough, it did. He then explained to me that I was likely to see a marginal drop in speed, moreso on the downstream, due to the higher noise tolerance, but that it should resolve the problem and the connection should never drop out.
He also explained the factors that can cause this, such as underground cables being near electic cables (my flats have electic cables right next to the telephone wiring), older wires, older phone lines etc...
He then asked me if I had any further question's or issue's, which I didnt, so he advised me to phone up if it happened again, thanked me for calling and wished me a nice evening and happy internet surfing lol.
Altogether the call lasted just over 4 minutes from when I pressed call until I put it down, it cost me nothing, and I found the customer service representative very polite, easy to understand (beauty of UK call centres), and very clear and precise in explaining about what he believed was the problem and how he would attempt to rectify it.
Sure enough, the connection is 100% now, hasnt dropped since he made the change. The speed is a bit lower, only around 9.5Mbps tops now downstream and 1.1Mbps top upstream, but I am as happy as a pig in shit with them speeds, and it is really refreshing to experience such great customer service!!!
Now I can believe all the reviews that have been posted all over the internet. I dont think a single person on Digital Spy has had a problem with them yet, they are all raving off them, and there are lots making the leap.
Maybe, just maybe, o2 could be the "perfect" broadband supplier. Not only a rock solid connection with fast speeds, but great customer service to back it up!
Well done o2, I have a LOT of faith in these guy's now and trust me, all these excellent review's people are posting on the net, are very much true from my experience so far!!
