SH2ac - Retentions?
 

Has anybody had any luck obtaining the SH2 ac through retentions by paying just the postage? - (same process as the SH2 last year)

Why do you want the SHUB2 AC? I bet all your wireless devices aren't AC

Re: SH2ac - Retentions?
 

no, but some will be

Re: SH2ac - Retentions?
 

From what I've read, it's a slight improvement over the existing SH2 (range)

and with an iPhone 6 on the way (supports ac) it's logical.

But regardless, for the sake of a fiver, Id be a fool not to ask - don't fancy shilling out for a expensive AC router.

What dose ac mean with the SH2ac?

Looking at http://community.virginmedia.com/t5/...s/td-p/2477075 trying to get a hold of one of those may indeed be self-destructive right now.

Mines been fine but I've swapped out a few with all 5 lights permanently stuck on bright blue and the wps button stuck on bright blue. In fact one was a regular sh2

Simple swap of hub, woukd like to know what causes it.

Sounds like that beta test is going well, then.

Re: SH2ac - Retentions?
 

Funny, who was it that said there isn't any need for testing because it was 'just' a wireless chipset change?

Re: SH2ac - Retentions?
 

Sounds like a manufacturing fault if some hardware is affected and some isn't.

Indeed it seems I reckoned without manufacturing problems from what's basically a PC card change along with some cosmetics.

I got it wrong. Happens to nearly all of us. Lesson learned.

It could be a software fault that's doing something to the hardware it shouldn't be

Re: SH2ac - Retentions?
 

It'd affect all SH2ACs if that were the case.

Re: SH2ac - Retentions?
 

Not necessarily, depends what it's doing. It depends on the circumstances of the failures. Could be pushing the hardware too hard during a reboot, for example, which would explain why it isn't killing everything evenly.

Re: SH2ac - Retentions?
 

How do you propose software pushes hardware too hard during a reboot? If a router can't handle hitting 100% utilisation for a while without having a hardware failure that's a manufacturing issue.

Damage during reboot is more likely due to the voltage spike and trough when power is applied. There can be latency before regulators kick in.

There are a very few cases where software can harm hardware, however these usually need the software to go out of its way to damage the hardware or the hardware to have some quite provocative switches available to control it.

The examples that come to mind for me are Stuxnet, though that worked on PLCs operating industrial processes so quite different from a cable modem router, and software that could kill Android devices by messing around with voltage regulation.

I wouldn't have thought the router firmware would have any control at all over low level functions capable of harming hardware, that'd be looked after by whatever is in the motherboard, individual cards, and SoC's ROM/PLA?

If the required buttons and switches are exposed to the router firmware that would be an 'interesting' decision.
