Help!!

Can one of the Mods or anyone please help me? I've had intermittent faults going on for what feels like about a year. Had a few new modems, engineers out 3 times and starting to lose faith in the Virgin service. I'm quite a heavy user in that I have maybe 60 odd devices connected and do use a lot of multimedia and large files over the network. It feels like the engineers that come out don't really understand the router or what the error messages mean on the router status page and as for the tech support team, well I cant bring myself to talk to them anymore. The symptoms are disconnects maybe 10 times a day, mostly brief but a pain, on speed tests we seem to be getting dropped packets (between 2 and 5%) on every test when connected to the wifi pod, if on the router itself it seems to be ok. Speeds vary, latency varies. On the Router page I notice a number of messages from DHCP errors maybe every other day to "US profile assignment change" which sometimes happens 20 times in one day, always swapping from one profile and back to the same one. Last engineer told me this was nothing to worry about but I definitely notice it degrading the experience. Then, maybe once or twice a week I get the router resetting out of the blue saying "Because of Kernel Panic". So frustrating because when it works it's great, but the inconsistency of it is making me pull my hair out.

Feels like it's a router problem first and foremost, but interested to hear people's thoughts? Also interested to know if people think a business connection with Virgin would see a better experience? IS it the same router? I work from home so on video calls a lot which is another challenge as the dropouts are a challenge! 

Can anyone help? And before you ask I've reset, rebooted tried all sorts. I work in IT so am fairly savvy although no network expert!

Any ideas welcome!

    You need to post all the Hub stats here to be checked. 

    60 wifi devices really calls for better wifi equipment than the VM hub and a VM pod.  Good wifi equipment isn't expensive. 

    How are ethernet connected devices working? 

    VM business uses a different Hub but everything else is the same.

      To be honest the Ethernet devices suffer too

    Looks like the hub is not fit for your use look to get your own router with 1Gb ports or better and put hub in modem mode.

  • Hello djgeurn

     

    We're sorry to hear of the connection issues experienced with your broadband service, we understand the frustration this can cause and appreciate you raising this via the forums.

     

    The number of devices you have is higher than most and could potentially cause problems depending on how many are active and using the connection at any time. From checking, quite a few of the devices show poor performance and a lot of these showing as offline.

     

    Currently, the speeds to the Hub are showing as averaging 1129Mbps download and 102Mbps upload, latency shows as 16.5ms and zero packet loss. There have been some disconnections over the last seven days up until 1.12am yesterday morning with none recorded since.

     

    I appreciate you have mentioned this has been going on for over a year, does the timings for the disconnections (particularly the last one) tally with the ones you have experienced?

      you may see 1129Mbps but sometimes its down in the 300's. We've just had a really bad half hour, maybe you could investigate that?

      Hi Robert, can you review the updates and advise on a solution please?

    As others have said - you are a heavy user you need to get yourself a good quality router and wireless equipment.  These are not too expensive - just ask on here if you want some pointers and how much you are prepared to spend in the £50-500 range

    Thanks for the replies everyone. If anyone has experience of good alternatives? I have the superhub 5 and 2 pods, coverage is really good round the house and speed is not the issue per se. It's robustness and consistency that I need!

    Would the business hub give better results or is it worth me spending the £500??

    Open to advice !

     

    Thanks again

      The problem is that we have no way of knowing if the issue is internal, ie is it the Hub/pods or external, bad connection, cable fault. If the latter then you could spend £500 or £5000 on your own equipment and it won't make any difference.

      But as ‘jpeg1’ posted five days ago, you need to post up the status details and logs for the hub to see if it does indicate an external fault, otherwise nobody here can possibly advise.

      As said.. post up the connection details as per below so we can look for issues.

      Whatever that reveals I still believe you usage and 60+ connected devices needs a better router than that in a VM Hub.  In strip downs its been estimated to cost VM between £20-30.  That's for inbuilt modem, switch, router and wireless transmission - two of those would cost far more individually and have much better specs and able to connect >100 devices simultaneously.

      ______________________________________________________

       Post up your Hub/network connection details in the format below and someone will check to see if there is a problem there.  In your browser’s URL type in 192.168.0.1  if in router mode or 192.168.100.1 if in modem mode.     No need to log in - just click on the “Router Status” icon/text at bottom-middle (Hub3/4/5) or top/right (SH’s) - of the Login page.

           Then… Navigate to these “data pages” and just copy/paste the normal  “Formatted Text” (not images) 3 FULL sets of data onto here – 2 tables from the Downstream, 2 from the Upstream, &  the 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 (you may need to click the "submit" button again). If character limits are “exceeded” - just do two posts

      Also, If you haven’t already, set up a free, secure and “offlsite”  - “Broadband Quality Monitor” to continually monitor the state of your connection and record any true network dropouts , latency issues, packet drops, etc - it will thus allow you to differentiate between those and simple wifi dropouts.  It does it 24/7/365 and it keeps a visual record of any/all of your network disconnections, useful data to have to match to the Network logs (in your Hub settings) and also in discussions with VM - note it will take a few hours to start seeing a sensible picture - post up the “link” to the “share live graph”.  Click the lower link (Share Live Graph) then, click generate. Copy the text in the Direct Link box, beware, there may be more text than you can see.  On here click the Link icon (2 links chain to the left of the camera icon) In the URL box paste the link you copied and then click OK

    So, update for you - I invested in an Asus router which seems to be working well. Seeing more robust connectivity and great speeds/latency and no packet loss. 

    However, still getting drops from the SH5 in Modem mode. here's what we're seeing on the SH page:-
