Wifi Problems Superhub 2
 

Hi all

Been having issues with the superhub 2 consistently since it's installation. All connections on the 2.4 ghz band drop regularly throughout the day requiring a reboot of the device. I am the only user in the house who can connect via the 5ghz band and have no such issues, also internet is still accessible via ethernet cable, I have tried changing the channel with the help of inssider to 'free' channels but to no avail.

I have spoken to virgin who say it is a known issue and have agreed to apply credit to the account, however I'd like to know if anybody had any other thoughts on the issue or had experienced this or similar issues with the new hardware, or perhaps problems stemming from sw update.

Cheers

Have you gpt the 2.4 GHz channel setting to "Auto"? That helps.

Also have you got it set for maximum range (I forget the number)?

Is the SH2 located behind or very close to a TV? If so move it.

From April through August I ran my SH2 in router mode and never had a 2.4 GHz drop.

Re: Wifi Problems Superhub 2
 

No probs here like Seph
Set wireless mode to 144 Mbps and Greenfield mode off for 2.4GHz

Re: Wifi Problems Superhub 2
 

All settings are as advised. The router currently sits around 2.5m away from the TV which, as far as I can tell, is the nearest source of interference.

Re: Wifi Problems Superhub 2
 

Have you tried a factory reset? You should also consider the other pc settings as well, it may not be the SHUB 2. For example, have you updated the drivers, what link speed are they connecting at?. How far away are the other PC's, what is the signal strength? What version of windows, is it fully patched? Have you tried going to the manufacturer of the wifi cards instead of the PC maker as generally I find that companies such as Dell have outdated drivers.

Here is a good place for drivers:

Get Netstumbler for testing wifi

It's most certainly not a problem on the receiving end, I worked diligently to ensure that before I contacted virgin. There are over 7 devices that this is currently affecting all with different hardware configs and operating systems, my own device the only one which supports 5ghz is also affected on the 2.4ghz band. On the 5ghz band at peak times I generally get around 40-50 mbs and at off peak times up to 90mbs.

I have tried resetting the device but it's no good, the virgin media rep i spoke to on the phone acknowledged it as a known problem.

All hardware and corresponding sw that I use I have checked for any issues and is always kept up to date.

Re: Wifi Problems Superhub 2
 

Well if you have tried everything, what do you expect us to suggest? I have thought out of the box for a number of other possibilities. I would suggest asking for a replacement! Other than that purchase another router.

I just find it hard to comprehend that you have 7 devices all dropping 2.4ghz and or it to be a known issue for the SHUB 2.

Re: Wifi Problems Superhub 2
 

In my opinion it's interference from somewhere, but a suggestion such as updating drivers is not out of the box thinking other than in the literal sense of the hub itself. I'm really just looking to see if anyone else has encountered such an issue.

The majority of the devices are laptops of the 6 other people I share a house with and the various phones they have all of which lose connection in that the connection is lost and attempting to restore connection results in no internet access until the box is reset and yet the 5ghz connection and wired connection remain to be functional.

Re: Wifi Problems Superhub 2
 

Do any of the laptops' logs actually state a reason for the disconnect?

Re: Wifi Problems Superhub 2
 

Nothing in any of the event logs, usually the network after disconnect is visible and can be connected to but it is unrecognised and unable to access the internet.

Re: Wifi Problems Superhub 2
 

Sounds like a firmware or hardware problem with the Superhub then. Which is not uncommon

Re: Wifi Problems Superhub 2
 

I got new super hub 2 as it was given to me free today by senior techical guy as my old super hub was overheated

The wifi 2.4G is far better than 5G in long distance. Poor wifi on SH2 in my view.

Re: Wifi Problems Superhub 2
 

2.4 will always have better range and penetration than 5. As much as they would probably like to, Virgin can't change the laws of physics.

Re: Wifi Problems Superhub 2
 

Senior Tech guy say to me power level on downstream are fine within spec between 0.00dB and 4.00dB and upstream between 45dB and 47dB.

I feel SH2 is no real difference to old SH in wireless performance. Pretty the same.

Re: Wifi Problems Superhub 2
 

Incorrect. 5Ghz allows ten times more transmit power than 2.4Ghz which more than makes up for the "laws of physics" range deficit. They just have to stop making cheap equipment.

Re: Wifi Problems Superhub 2
 

The SH2's wireless is unquestionably better than the SH1's. Never mind that it's dual band, the range is definitely better and throughput at range is a lot better.

That's an interesting one, I wasn't aware of the 5Ghz power thing. Still, is it anything to do with cheap equipment or so that we don't get an influx of routers blasting noise onto the nice clean 5Ghz spectrum?

Then explaining why I getting poor wifi here: https://www.cableforum.co.uk/images/...2013/10/36.png

Super hub 2 is worse than super hub

Re: Wifi Problems Superhub 2
 

It's wireless, there's any number of possible factors.

Re: Wifi Problems Superhub 2
 

Your ping is crazy high, have you chosen the nearest to you?

Re: Wifi Problems Superhub 2
 

Tech guy coming out tomorrow to go back to old super hub.

Re: Wifi Problems Superhub 2

Are these look good on super hub 2?

Re: Wifi Problems Superhub 2
 

Thought you were going back to the old hub?

Re: Wifi Problems Superhub 2
 

No, the tech guy say super hub 2 is the only way forward as virgin media going to get rid of superhub slowly. Because they going to bring in 200 and 400 meg soon.

Re: Wifi Problems Superhub 2
 

Considering they both do the same number of channels, that doesn't make any sense at all.

Re: Wifi Problems Superhub 2
 

I can get WiFi that bad if I really try.

Re: Wifi Problems Superhub 2
 

My 2.4 wireless has gone down tonight for the first time since upgrading to the SH2.

Had to reboot the router.

Re: Wifi Problems Superhub 2
 

Faster CPU and wireless to better handle the higher speeds locally?

Doesn't help if you have a modem doing 10 gigabits if the router component can't actually deliver that to the user...

Re: Wifi Problems Superhub 2
 

Good point, there is that. It does seem a bit far-fetched though, coming from the above.

Re: Wifi Problems Superhub 2
 

What isn't?:p:

Re: Wifi Problems Superhub 2
 

tech guy just change to 144 channel 9 on 2.4Ghz wifi and turn off 5Ghz as he say it not needed. But 2.4Ghz only getting 42Mbps on wifi on iphone/ipad. I try 5Ghz but still the same 42Mbps no real difference.

What are your setting gasdfdsaq on both 300+450?

Re: Wifi Problems Superhub 2
 

I don't use ISP supplied routers other than for testing - but where I do I always set 40Mhz mode (300Mbps) on both 2.4Ghz and 5Ghz.

Mind you crApple devices do have a tendancy to dislike 40Mhz mode operation, especially at 2.4Ghz.

Re: Wifi Problems Superhub 2
 

My Apple devices (iPad, iPhone 5S) are quite happy with 40MHz operation on the router (defined in Airport Utility as "Wide Channels")..

BTW my router in this case is the Airport Extreme which doesn't support 40 MHz for 2.4 GHz.

Re: Wifi Problems Superhub 2
 

Why on earth is 5ghz "not needed"? That has to be the most braindead thing I've heard a VM tech say yet.

Still getting back on point, 42Mbit would be about right if your devices are connected via a single spatial stream at 20Mhz. I don't know enough about Apple stuff to comment on that.

Re: Wifi Problems Superhub 2
 

That would be my point. The router hardware *does* support it, Apple just won't allow you to turn it on. Similarly even if you did turn it on, your devices would still have it disabled. Last iPhone I came across had it permadisabled even on 5Ghz though newer ones seemingly don't.

Re: Wifi Problems Superhub 2
 

i have turn 5ghz off on mine as no devices in my house pick it up so waste of time having it on

Re: Wifi Problems Superhub 2
 

I have an ipad and my android phone and my apple tv all pick it up. my problem right now is that i cant connect to my vpn on ipad over the connection, i can on my mobile connection if i tether it to my ipad.

not the SH i think its just me lol
