@jbrennand

thank you sir.

yes indeed we have a hub 3.0. Semi detached house tho, flats near by if that matters..?
Interesting how you say its a generally problematic device and yet I get responses from Virgin saying sorry you've had trouble for 6 months (that could very well be a result of these - AND they most liekly know it !) but we're not going to do anything about it, go whistle... 😞

Regarding 'getting your own equiptment'.. is that something you can advise me on please sir. I have a good general tech knowledge... probably fairly outdated.. but not igorant... I'm more than happy, especially with the FU attitude of Virgin to spend my money elsewhere...

going to get some wifi boosters in the mean time to ease the problem but I dont believe for one second they will solve the problems we've been experiencing.

thank you again.

If the ethernet cable connection is stable and your problems are just wifi related then you could first try this to see if it improves the Hub3's performance. You can always "pinhole" reset it back if it doesnt help or you dont like like it.

Go into the Hub3 settings. Type in http://192.168.0.1 into your web browser’s url box and login with the settings password (not the wifi one!) on the Hub's base sticker (or your own password if you changed it). Then in Advanced>wireless (I think) tick the "disable channel optimisation” box - and save settings.
Then, go to advanced>wireless>security, and rename the 2.4 & 5 GHz network ssid's. Just change 'em to whatever you like and something that will differentiate them (e.g - bettrxx2 & bettrxx5) -- use the same password for both if you like, Then, apply settings and restart the Hub. Your 2 wifi networks will now be clearly separated - and you can then select the network you want to connect to individually from the "available networks" list on each device.
You will have to reconnect all your wifi devices as they are now seeing new networks with new passwords. The5 GHz band is usually better and subject to less interference (and is better for iDevices and V6's) than the 2.4 one - although that one has the better "range" and some older/cheaper/dumber devices can only use this one.
You could also use a wifi analyser App to check which 2.4 channels are being heavily used around you and move yours to one that is least so (choose one of the non-overlapping channels 1,6,11).

If that doesnt help there are a number of options to improve the house wifi.
VM's connect App and "boosters" have worked for many people - or you could just purchase your own. Devolo are highly thought of and offer devices with high speeds and both wifi & ethernet cable options.

You could also just buy a good quality wireless access point or 2 (see the Ubiquiti range as good examples) and connect it to the Hub by ethernet cable and site it where it/them will do most good - e.g. upstairs?
Or you can go the whole hog and put the Hub into modem mode and get your own wireless router. I did this, albeit I still had some "dead spots" so also I added 2 cheaper wifi extenders to cover them. Some get a wifi router and then dont need to do that - costs vary between £70 for a basic entry model up to £300+ for a high spec gaming router.
Many say that this route is overkill and less flexible than just buying a (non-wifi) router (again see the ubiquiti range for examples) and then adding in wireless access points where required.

Finally you could get a good "Mesh" system connected to the Hub3 to give you whole house wifi coverage. These usually have 2/3/4 units that connect to the Hub and then the "slave units" piggy back the wifi connection around the house
See Techradar, Techadvisor & Expertreviews websites for recent reviews of good examples of all options.

hmm the hub was already in that mode but the engineer who came last night said that caused problems and reset it back to a non-split mode..

I wonder if the power level changes he up'd improved things and the hub changes he made, made them worse again then !?!?

[jbrennand]

Post up the Hub data then

In your browser’s URL box type in http://192.168.0.1 (or http://192.168.100.1 - if in modem mode) and hit return. On the first page up [there should be no need to login if you have done so before] click on the “router status” icon/text at bottom-middle of first page up (you may need to scroll down to see it) and then copy/paste 3 FULL sets of data onto here – from the Downstream, Upstream, & Network Logs pages.
Don't worry too much about the formatting it can be easily read & DON’T include personal data or MAC addresses - blank them out - if you copy/paste the data, the board software will do this for you.

i did also notice - i think - prior to re-splitting the hub that the bedroom v6 had automatically connected to 2.4ghz and not 5

now its on 5

Data looks good to me all within recommended limits - others may want comment
