At the beginning of June I upgraded my package from the 200Mbs to the Ultimate Oomph 600Mbs. When my package was first upgraded I was getting the expected speed. Last week my speeds dropped to around 150Mbs give or take 20Meg. I contacted customer service and the guy I talked to told me that there was a problem there end but would fix it and to give 24hrs to settle down. 48hrs passed and there was no improvement so I contacted VM again, this time the operator told me every thing was ok but to reset my router to defaults then he carried out some tests his end and after half an hour or so told me it was third party equipment that I had connected that was causing the problem. When I checked my speed after he had done whatever he had done I found it now to be only 10-15 meg. When I told him this he insisted it was the third party equipment and there was nothing he could do to fix it. After the call I disconnected all the third party devices and turned off everything that was connected by wifi. I then checked my speed again and found that it was still 10-15Mbs on wifi and 75 on a wired ethernet connection. I have been monitoring since and at one point my speed dropped to 0.43Mbs. These things don't really mean a lot to me but the network log doesn't to good. Any help and advice would be very much appreciated.
Thanks in advance to any one that can help
