cant see how blaming idnet about my internet connection is wrong?
i pay them to supply a broadband service which recently has developed problems,they say the problem is hardware owed by myself to which i dissagree.
They are giving you their best advice, based on the evidence they see from line tests. If you are confident that it's not your router or wiring, ask them to arrange a BT visit, but be aware that if no fault is found 'BT side', it will cost you £160.
As to exchange capacity, when ADSL2+ launched, BT were caught out with insufficient capacity for the uptake, and the result was months of robbing Peter to pay Paul, good speeds followed by bad. Yes, IDNet did have some congestion issues, but only because BT were a year late delivering the extra capacity which had been ordered. Since then, to my knowledge, the network has always had headroom, and as has been stated, IDNet ordered extra bandwidth to cope with the World Cup. This is an expensive process for any ISP as although the event only lasts a month or so, they have to pay for the bandwidth for three months, in other words, it's still there. Exchange congestion and hot VPs are all too common, we see them regularly at Netters.
If you don't trust what IDNet tell you, you have the option of asking for your MAC at any time. It might even produce an improvement if it results in a routing change at the exchange, but it doesn't mean IDNet weren't being honest with you.
