Issues with 2.5Gb Unmanaged Switch and 2.5Gb Port

I recently got my Hub 5 with gigabit internet. I was using a gigabit switch with no problems but would only get 950Mb to my 2 PC's. Then I purchased a 2.5Gb Switch, connected it to the 2.5Gb port and for a week had 0 problems. My PC would get 1150Mb while the other still only received 950Mb as it's motherboard is too old. Then suddenly my PC's would not be able to access the internet. It just shows unidentified network or will show it connected but have no access to the internet. The weird thing is that if I connect the 2.5Gb switch to the 1Gb ports it works but doesn't use the full speed. Whereas if I connect my gigabit switch to the 2.5Gb port, that works but caps out at 1gb.

I even thought my 2.5Gb switch was faulty so I returned and got a new one and it has the exact same issue straight away but this time it didn't even work for a week. Just to be sure I connected the same cable I used from the router directly to my PC on the 2.5Gb port and my PC gets the expected 1150mb.

Does anyone have any idea on how to troubleshoot this or what could be wrong?

    The silence from VM says it all really.

    6 months to acknowledge an issue then another year before a fix based on previous experience....

    Unless it was deliberate to stop people using a switch to the 2.5gbps port; in which case, no fix. A HUB4 would not have a 2.5gbps port and some VM staff still peddle that HUb4 is fine for gigabit as connection shared with WIFI devices. Many people asked for HUB5 due to 2.5gbps port so it might be management's idea of stopping it.

    Wouldn't it be good if the UK LG (aka VM) were less secret squirrel and told us what was in the firmware upgrades.

    Several years ago, I let slip in this Forum what was in one of firmware updates (we Superusers - aka VIPs - were in the know) and I was promptly defrocked.  Secret squirrel.

    Well i just bought a 2.5gb switch and plugged into the 2.5g VM Hub 5 port and lo and behold it was terrible or just plain not working. Thought my switch or cables defect but no its the Hub 5 2.5g port. I tried another port and working fine. So it seems theres no fix to this? Absolutely shocking Virgin Media.

    Hi guys, i have a hub 5 with a 2.5gb slot, i also have 4 computers (all ethernet cabled) all with 2.5gb nic cards, when i transfer files, the LAN is completely working fine, BUT i have no internet connection at all. Thats obviously when i have it plugged into the 2.5gb slot in hub.

    If i put the cable into any other port on the hub, i have 1gb LAN and internet all around. (when the cable is connected to the hub 2.5gb, it goes into a 2.5gb switch, and the port colours all present the 2.5gb connections to the other 4 computers, so there is only one cable into my virgin 5 hub)

    So, what am i doing wrong that i cant access internet if i use the 2.5gb port? That includes wifi. In fact, i cant even access 192.168.0.1 anymore unless i put the cable into one of the other 4 ports in virgin hub.

    Can anyone advise please, i hope iv explained good enough, many thanks

        Any danger of this being fixed (again) @Steven_L?

        I've literally printed out the solution - please can someone help?

    The solution to this problem is on the previous page - it was a firmware problem.

    My router updated again this morning and REINTRODUCED the same fault, taking out my internet connectivity until I used a 1Gb port instead of the 2.5Gb. (DOWNgraded to Version LG-RDK_7.6.20-2306.5)

    This was a known problem with a known solution, and you've gone and done it again!  I'm thinking you've re-enabled the green Ethernet for that port in the firmware.

    Sadly, nobody at VM seems to know what a 2.5Gb port even is - let alone how to fix it.  My contact at Virgin (the real Virgin) is away so will prob have to wait until he returns.

    Please down(up??)grade my router to Version LG-RDK_8.10.26-2309.3 which does not have this fault.

    Why oh why do Virgin Media not test these things properly?  Why do you not have testers selected from your users who would probably do a better job of finding faults?

    Your internal testing is obviously inadequate.  Last time this problem cost me about 4 hours and lots of rudeness.  It cost VM £50 for that.  How does this make sense?
