On the 3rd of June I noticed that my speeds would drop from 7mb (my IP profile, 8128 sync) down to 1.6MB. My upload speed would not change, neither would my ping while playing games. The router (a TP-Link) would not disconnect when this happens. I would continue to stay at 1.6MB download speeds until I re-synced my router (be it restarting or simply removing the telephone cable) at which point it would jump back up to 7MB for a few hours/days. It didn't happen at any particular time either, it could be 2am, 11am on a weekday or 3PM in the afternoon, it didn't matter.
Over the last 11 weeks, I've had 3 replacement microfilters, a replacement Livebox router, a replacement TP-Link router (4 routers tried in total each with the same problem), I've had 4 engineer visits (inc. replacement master socket and a replacement line and pair to the exchange (which boosted my speed but the drops were still present).
I'm currently at the end of my rope with Orange and filed a complaint last week to ISPA. A relations department manager from Orange contacted me (UK based) but nothing has changed. I've currently spent £65 on phone calls to orange over the last two months and to be honest, the connection is probably worse than when I first called. It was suggested that electric interference could be the culprit but both BT engineers were adamant that it would also effect my attenuation (which it doesn't) and the rest of the router stats (ping and upload, again, which remain constant).
Where do I go from here? Generally, the customer support is extremely rude and I'm left having to repeat myself over and over. If I dare miss a phone call then they close the case because it's listed as a speed issue, of which they assume is fine excuse on their end it shows I'm connected at 8128Kbs. Does anyone have any advice for me? Again, when my router drops in speed the attenuation and rest of the stats do not change, it's as if I'm being capped (download wise).
Thanks for your help!
