Hub 5 glitch DHCP

Thought I would post this as there have been other similar posts. I have the hub 5 as my main router. I have 3 switches that plug into each one of the ethernet ports before feeding various devices. One connects to the 360 main box. Another switch acts as my secondary WiFi, and third connects the 2 other mini boxes . I've noticed that when using a PC or laptop connected to the switches, if they go into standby and then wake up, it can take a few mins before internet comes on. If the PC is off and then turned on it's fine. The work arround is to disable the ethernet port and then re enable it and it works. Very strange and can't work out why. The virgin boxes don't have any issues and connected indirectly via the switches.  Anyone know why this is. I've put the hub 5 in modem mode and despite having a draytek vigor router, the WiFi is 5 not 6. The hub 5 is fine otherwise and this minor glitch I can put up with, but would love to know the reason.

    Are the switches all unmanaged and have you swapped out Ethernet cables?

    Have you connected a device directly to the Hub 5's Ethernet port without going through a switch? If the issue doesn't occur, it points towards a problem with the configuration or functionality of the switches.

    Another thing: go to Device Manager > Network Adapters, select your network adapter in use, click on the Power Management tab, uncheck the checkbox: “Allow the computer to turn off the device to save power”. Click on the Advanced tab and disable any options concerning energy saving, Energy Efficient Ethernet (EEE), Green Ethernet etc.

      The ethernet cable is pretty long , it's cat 5e and was laid back in 2005 and runs under floorboards and in walls. I don't think it's that as the switches are all unmanned and I can stream stuff and no interruptions whatever. I'm pretty sure it's a DHCP lease thing but not sure why it would be like that.  I had sky prior and had their q router and could wake up the pc and it would connect. Sky's internet is terrible but that's a topic for another day. I have a PC connected into the 4th ethernet port on hub 5 for trouble shooting but it's always off at the mains. Maybe I should leave it and let it go to sleep and see what happens? WiFi isn't affected however.

    There have been reports on the board of DHCP problems with the hub5. My suggestion is to give the devices a true hard wired address in the device and see if that helps. It may not as the way DHCP works it still contacts the DHCP server even with a hardwired device.

      Actually the Draytek Viggor router that I am using as an expensive switch has a static IP address so I can access the internal menu should I need to. What I did was to allocate the IP address outside the DHCP pool so there isn't any conflict. But oddly enough there is a PC connected to that and it runs windows 11 and when it boots up it takes a minute to connect to the internet.

        As your Hub 5 is in modem mode, then you should connect the Hub 5 to the Draytek router and then connect each of your switches to the Draytek, enabling the DCHP within the Draytek. You will need to alter the port setup in the Draytek so that all its outbound LAN ports are within the same subnet. The Draytek routers IP would also become static due to it being the router. I wouldn’t have thought the Hub 5 in modem mode would be a DCHP server. I have a hub 5X so can’t run it in modem mode, but my Draytek is my DCHP server and is running a couple of managed switches.
