Newbi help needed with VLAN performance MS108EUP and GS110EMX
Just updated my home network by adding a NETGEAR MS108EUP and GS110EMX so I can have 2 VLAN's connecting my basement and upper floor with both my internet network and the Google fiber network. I think after a lot of reading/learning that I have the VLAN's working, I have the internal network/admin as the default VLAN 1 and the connection to the Google fiber router on VLAN 2 and on each switch depending on the port the host device is
connected to one of the two networks.
As part of my testing on two PC's which are connected one to each VLAN I did a speed test to make sure I was getting the throughput expected. VLAN1 is 1000Mbps and VLAN2 is 2500Mbps on Google Fiber 2000.
I have not made any other changes to the default switch settings.
When I do the speed test to Google, I see the throughput on download hit around 700Mbps on the PC on VLAN 1 and 1700Mbps on VLAN2 but after a couple of seconds the test fails with a socket error.
I didn't have this issue when using the NETGEAR GS110MX unmanaged switches that this new solution replaced.
Anyone know if there is something in the switch(es) configuration that would cause this issue?
Thank you for any help!
Quick update.
First, thank you for those that offered guidance and help!
After trying to get this working a couple more times I ended up calling Netgear support who also couldn't find anything wrong with my setup or configuration. We concluded the switch was not working correctly and so I ordered a new one and now everything is working as it should, so the MS108EUP was the issue.
I ended up getting a second GS110EMX rather than replacing the MS108EUP with the same switch as I found several other reviews that seemed to have similar issues with that switch, and I don't need the POE feature.
Thanks again!
Mark.

Two switches. Wild guess one in the basement, one in the upper floor.
More wild guessing, one physical network connection between the two switches. Probably 2.5GbE because that's the max the MS108EUP can do.
More wild guessing, two VLANs configured, VLAN 1 and VLAN 2. Configured how to the different networks resp. routers resp. PCs.
What makes up VLAN 1 to be the default? Probably using the link with untagged frames (thus default?) for the normal Internet LAN (Gigabit), and some tagged trunk for VLAN 2 for the Google Fiber network LAN?
Definitively confused about the point where you state "and on each switch depending on the port the host device is connected to one of the two networks."

What has changed to this?

Please put up a list of what you think you have connected and configured.
And why/how should the previous unmanaged GS110MX made this configuration work - considering there are at least two networks, two LAN, two LAN IP subnets , ....?
VLANs don't make connections - Ethernet links (or for the sake fiber links) do. On an Ethernet link, you can operate multiple VLANs which carry traffic or frames, and ensure this traffic is kept independent from the other networks.
By rule of thumb, what I would suggest:
- One physical Ethernet link between the two switches, or in a second stage two Ethernet links in static LAG - the later makes the VLAN trunk config more complex to understand
- The ports connecting to this trunk, configured as [T]agged for each VLAN 1 and 2 ... that makes the trunk carrying both VLANs in tagged frames, for example port #8
- Define multiple access ports on both switches for each of the VLANs 1 and 2, for example
Port 1...3 VLAN 1 [U]ntagged, PVID 1
...
Port 4...6 VLAN 2 [U]ntagged, PVID 2
...
These ports 1..3 on both switches make up network connections (like a cable) for VLAN 1, resp. ports 4..6 on both switches make up network connections (like a cable) for VLAN 2. Like direct connections to each router LAN for example (including each router).
Thank you for the time to help me. I not sure what you mean on some of that, so I did a before and after diagram and the VLAN config screens. The network is how it is due to building physical limitations. I wanted to use VLANs so I could have both the 192.168.3.x (internal network) and 192.168.2.x (Google fiber router) on the same physical wire between floors 1 and 2 so I could have wired network on floor 3. Everything except one PC is on the internal network 1Gbit and that one PC is on the Google Fiber network on 2.5Gbit.
It seems everything is working, sort of, as the devices are getting the right DHCP addresses, but I am getting odd behavior such as downloads failing, occasional buffeting on streaming, and can't do any speed tests without it failing after a couple of seconds.
MS108EUP GS110EMX
Port 1 Google 2.5Gb (VLAN2) Port 1 Synology Router WAN (VLAN2)
Port 2 Trunk to GS110EMX (VLAN1 and 2) Port 5 to GS116NA (VLAN1)
Port 4 To GS305E (VLAN1) Port 6 to GS308 (VLAN1)
Port 6 To 2nd floor Synology extender (VLAN1) Port 7 to Synology Router LAN (VLAN1)
Port 9 to GS110MX (VLAN2)
Port 10 Truck to MS108EUP (VLAN 1 and 2)
I hope that helps explain my situation and once again thank you for any help and guidance.
Forgot the config screens
After rolling back due to the issues I figured I would start again planning this solution! Here is a simple view of what I am trying to do with these two new switches. Basically, I have one cable between 2 floors and want to use that as a truck to carry traffic for both VLANs - is this possible and if so, what did I do wrong with the configuration?
Yeah, that should work as long as you do not need access from VLAN2 to VLAN1. Also, it usually means double NATting while accessing Internet from VLAN1, but your Synology router may be different.
