General FAQ on Virgin Media's WiFi Sharing - Page 2

In regard to the possibility of interfering with your home service:

Afaik, VM the firmware has QOS that favours the home service flow rather than the hotspot flow. There is likely devil in the detail because downstream comes from somewhere else than your SH2 but when it starts on 01-Sep I will do some experiments.

The above refers to WiFi contention. If both service flows are on the same 2.4 GHz channel, then there is potential for wireless contention.

Will use same channels on both 2.4GHz and 5GHz. To do otherwise requires multiple radios.

5GHz is not on offer for VM's "FON" service.

Good thread, thank you.

It is a pity that VM when they announced WiFi and speed initiativs and upgrades so close together that they didn't think through what people's instinctive reactions would be. Better that they had done an FAQ such as yours.

Will this work if you're in modem mode on an SH1 ? What if someone downloads/does something illegal using your connection?

Don't think I've ever picked up anybody elses signal in my area so will probably opt out. All those signals flying about can fry your brains

Unknown, guessing it will work though.

It doesn't ever trace back to you. Completely separate connection.

Fair enough, but it may come in useful if you ever travel somewhere

Purely personal, maybe slightly selfish viewpoint - but I'll probably be opting out of this.

We get excellent 3G & 4G coverage from our EE mobiles, and our data allowance barely gets touched as it is, so I can't see that adding random WiFi hotspots to the mix is going to improve our mobile data experience. I've experimented with using WiFi on the London Underground to "prove that WiFi calling works", but I get that included via my EE subscription anyway.

And yes, if there's the slightest risk of our modem's uncontrolled "public" network affecting our personal network - then I know which is going to lose out.

As many have said, the devil's in the detail.

Kushan · 22-08-2015, 21:18

Indeed. As far as I can see, with all the information we have available, the ONLY way your personal connection will suffer is if you're using the Superhub's own wireless.

Currently in modem mode there is no wireless from SHUB1. Also SHUB1 is only single band either 2.4 or 5, and with internal antennas has pretty lousy range, so there's not be much opportunity to share it from outside your property. But I hope it can be enabled so you get the benefit of sharing when out.

Given the lousy firmware on SHUB1 in routing mode, I find it difficult to believe its going to be touched - wouldn't it be easier to give everyone a Fonera type device?

The SH1 is not being used for Public Wifi - at least not in the current trial phase.

Plus Public WiFi will be on the 2.4GHz frequency range so in theory, the SH1 could be used. But it is a useless wireless device and even VM couldn't be that stupid as to put Public WiFi onto it.

Kushan · 22-08-2015, 22:59

They could and nobody would notice because nobody would be able to connect to the damn thing.

I do wonder if the SH3 will have additional antennae built into it just for wifi sharing.

Sephiroth · 22-08-2015, 23:15

I doubt it, Kush. That's what modem mode is for.

I mean the SH3 will have modem mode? It will, won't it?

virgin email this morning Farnborough GU14 Going FREE WIFI September .well they
will have to improve a lot our current service no end of visits by Techs still not fixed

Sephiroth · 23-08-2015, 09:20

This is what the BQM has been like since the WiFi trial SSID started to be broadcast on 17-Aug-15.

I might sign up for this then given my SH1 in Modem mode has little chance of being able to share its connection (however I can blag other peoples). Maybe they'll be a rush of punters asking for a downgrade to an SH1 !
