I sent in a complaint and i'm getting sent a free 'install yourself' 2AC router.
I'll let you know if it fixes the issues we're having on the SH2, forcing us to use the 5ghz channel on 54mbps. (Firmware update issue)
I did some research and i'm seeing some good things. Here's what i found.
• Virgin Media has been slowly improving its routers since its Super Hub cable router. First it introduced dual-band 2.4GHz and 5GHz support with the Super Hub 2, and now the Super Hub 2ac has 802.11ac support for a much-needed improvement in wireless speeds.
• In our tests the router's 5GHz performance was definitely superior to that of the outgoing model. We tested the router's transfer speeds using a laptop with a built-in Intel Dual Band Wireless N-7260 adapter. With this setup we saw 167.8MBit/s at 10m and 79.6MBit/s at 25m - far faster than the 74Mbit/s and 13Mbit/s we saw from the old model, but nothing that spectacular. Those speeds bumped up to 181.8Mbit/s and 121.1Mbit/s respectively when we switched to a Huawei E367 external dongle, which is still middle-of-the-road performance.
• The Super Hub 2ac is a Netgear device underneath the Virgin branding, so we used a Netgear 802.11ac adapter for testing 802.11ac speeds. With this adaptor plugged into our laptop, at 10m we saw a superb 326.2Mbit/s, and 181.8Mbit/s at 25m was faster than we saw from 802.11n in the 10m test. This is a seriously impressive result and welcome news for anyone with 802.11ac hardware they want to connect to the router.
• 2.4GHz performance wasn't quite as fast as the previous model at 10m range; the Super Hub 2ac managed just 15.6Mbit/s, compared to over 30Mbit/s from the previous Super Hub. However, 10.3Mbit/s at 25m was a definite improvement, as the previous model failed to hold a stable connection at that distance.
• Simultaneous 2.4GHz and 5GHz Wi-Fi is still available, so you can connect newer devices at the same time as older, 2.4GHz-only models. With five internal aerials (two for 2.4GHz and three for 5GHz), the Super Hub 2ac has a theoretical 1,300Mbit/s maximum transfer speed. We might not have seen anything close to those speeds in our tests, but considering we conducted them in an office with high electrical and wireless interference, the router should perform well in a less electrically-busy home environment.
• The Superhub 2ac will be provided free of charge to new cable broadband customers on all Virgin's broadband packages. As is standard with Virgin Media kit, you don't actually own the router, so you can't sell it on should you upgrade, but you do get the peace of mind that the company will replace it should it fail. New customers may also have to pay an installation fee, with someone coming to your house and setting up your connection.
• The Superhub 2ac is a surprisingly capable ISP-provisioned router for those only looking for straightforward internet access and networking. Anyone looking for more advanced features, such as network storage, should look at setting the Super Hub to modem mode and using a separate router, however.
I'm being sent one too. They've just become the standard for new customers I think. I simply explained my issue and asked if it was possible to be sent one. He was really good, and arranged for one to arrive next week. There really are helpful advisers out there!
What if i open all the ports needed, like i've done on the SH2. This will make it open forever?
From the tests I've done, no. It won't really make any difference. I even have my console in the DMZ, but at odd times the NAT will still go to Strict, which makes no sense whatsoever, as the DMZ bypasses the NAT.
