The concurrent dual band works really well (worth £50?)

I'd say if VM felt the SH1 was 'worth' £30 then the SH2 is well worth £50.

Be better spending £50 on a proper router, way to many bugs at the minute.

They were charging £75 at one point for the SH1, which is hilarious.

Wow. I honestly weren't expecting them to actually implement that correctly.

Bravo. This new Shrub is not only a serious improvement but actually looks professionally done as well, rather than an amateur box-ticking botch job like the last one...

See all those hundreds of businesses with professionally installed wireless networks where they are all attached high on walls or the ceiling? Seen any who installed their wifi access points on the floor?

Of the 72 wireless connections I can pick up with a scan there's 1 on the 5GHz band.-ME!

Sure, last time I did a "drive test" I found out of 380 Superhubs, all but one were on 2.4Ghz. However since consumer grade 5Ghz signals don't travel as far, that's not an entirely fair comparison.

Personally I'm still surprised when I see professionally installed wireless networks (hotspots, hotels, airports, etc.) that use 5Ghz, even then they are still extremely rare. There's only three I know of in Edinburgh. Two belong to universities.

Qas, i have the SH2 and have my apple stuff connected to the 5GHz and other older stuff to 2.4. Is there any benefit to this or should they all be on 2.4?

They charged £75 for the old hub too! I went to a customer who paid it as sales said it has the best wifi

anyone have an answer to the above ?

It's known to be < 2.5 ampere draw in router mode (that's the PSU spec); someone AFAIR has measured < 1 ampere drawn in modem mode. The simultaneous dual band has upped the router mode current draw from the SH1.

The SH2 doesn't have a WOL feature (to trigger a PC)

Thanks Seph, any idea what the watts draw is ?

Shame about WOL, I really miss that feature.

Sephiroth · 05-05-2013, 18:11

Multiply 240V by the current - gives you the Watts.

As much of an improvement as the SH2 seems to be, I don't think it'll ever be a replacement for a dedicated router. Stuff like WOL is very much not needed for 99.9% of virgin customers.

No.

600 watts would be a little ridiculous for a modem and router, you want to take the voltage output of the PSU and multiply it with the amperage output of the PSU.
In this case its 12v x 2.5a = 30w max or x 1a for 12w.
The PSU itself of course can still be and most definitely is pulling more power from the wall than it is outputting due to inefficiencies I honestly have no idea about the efficiency of this type of power supply but would use 80% efficient as a general rule.
So adding another 20% on I get somewhere south of 36w for router mode and 14w for modem mode pulled from the wall. This of course also depends on how much work the device is doing and would be absolute maximums.

Your amperage x 240v is correct for anything that takes 240v directly (although the target voltage in the UK is 230v).

VxA=W. That is set in stone.

However what is the VxA being drawn from the mains to the adaptor, that is the true consumption.

As the current for the S/H or any device using a power adapter is drawn fron the mains and induced by the coils in the adapter then it is the adapters current draw from the mains which should be measured.

I look forward to your reply!
