Join the club yes peak time issues have been evident for the past 23mths on and off , used to only see issues on a Sunday and or Monday evening times correlated to the plusnet usage charts , as the useage increased throughput would typically start fluctuating and generally decrease in particular when using single threaded mode on down or even upstream in some cases , this Sun /Mon peak time issue has more recently become a bigger problem for some of plusnets customer base both fttc and adsl customers have been affected by it as it over the past few months has started to cause issues on an almost nightly basis
The fact that by gateway hopping which can sometimes take multiple attempts in order to eventually to connect to a unsaturated endpoint which can be on the same gateway but requires a drop of PPPOE session to enable this , the fact that by doing this often will provide normal or near normal levels of throughput to be restored is certainly an indication that this issue lies within plusnet's or BTW's remit as it's network interconnect related, plusnet have been quick to dimissis this as being down to their networking , and have attempted to blame it on other things like the customers connection , asking customers to report it as a fault , when this clearly isn't a line/or customer equipment fault , one customer followed their advice and they ran their end to end line test which of course detected nothing and closed the ticket, Plusnet are jokers at our expense, Reading the ADSL forum it would appear that they even booked an OR engineer for this type of issue, of course he reported a RWT problem is who is paying BTOR for these visits, I for one won't agree to even the possibility that i may be charged should they wish to send out a BTOR engineer in my case, So if they are going to put it in writing that they will swallow such a charge then bring on the engineer visit waste of both mine and the engineers time imo The PPPOE session issue does occasionally rear it's head i think it's got something to do with the hardware in use
BC i can confirm using a thrird party DNS makes zero difference to throughput, i have never used Plusnets ropey DNS servers and never will
