I had a very unpleasant experience (still have) while upgrading to a 1gig with Virgin media. I used to be on the M500 package with Hub 3. Everything worked very well, and I used my Hub 3 in modem mode with my Netduma r2 router. At the end of my contract, I decided to upgrade to 1 gig as it was pretty much the same price. The gentleman on the phone told me that with the upgraded 1gig package, I will get the new Hub 5 router. He has told me that he checked on his side, and Hub 5 router is in stock. The parcel with the router misses its original delivery date, and a couple of days later, I receive my new router. It ends up being Hub 4. I immediately call Virgin, and the lady on the phone tells me, "oh, you were supposed to get Hub 4". This really frustrated me because it was a lie. Even on my bill, it shows "Virgin Media Hub 5 (Upgrade) £0.00".
The whole thing is made even worse because online gaming is now pretty impossible because of the lags. I didn't have this issue before on m500 and hub 3. However, now every time I am on an online match(for example, COD), I would get random package losses, and I would lag for a couple of seconds. I've tried using the Hub 4 in modem mode and router mode. Nothing helps.
