Network switch selection for VLAN design
I currently have an unmanaged network consisting of a 24 port switch, 3 - 8 port switches, a Netgear RS series router and a cable company supplied modem. Several IOT devices reside on this network, and I would like to redesign to include managed switches to facilitate the use of VLANS to segment my IOT and streaming devices. A rough picture of the current design is below. My Questions. Should I consider replacing Switches A and B with new managed switches or can I get away with replacing the 8 port Port switch at B and put a new 4 port switch between the IOT devices and my main 24 port switch. ( and no, because of location and wiring constraints switch B must also connect to router. For the purpose of establishing simple VLANs for IOT, would the GS 3xxseries (GS 308E and GS305E) easy smart managed switches from Netgear work?M4300-52G-POE+ Bricked Recovery Method
Anyone knows how to recover from a power outage that bricked my M4300 ? M4300-52G-POE+ We had an outage. Power came back on, then the unit boots but none of the 52-ports came back up. The OOB port lights up when plugged into, but nothing. Then I console it and got the readout. It didn't even get past port0 and stalled out.

I've been going back and forth with Netgear support for over a week about this and I'm honestly at a loss. I'm hoping someone here can tell me if I'm crazy or if what they're telling me doesn't make sense, because it really doesn't add up to me. My Setup Switch: Netgear GS110EMX (firmware 1.0.2.8) Port 1: Internet uplink (1G, connected to router — standard fiber ISP) Port 9: Mac Pro via OWC Thunderbolt 4 to 10G Ethernet Adapter Port 10: Asustor AS6508T NAS (10G) Cables: Cat6A throughout This is exactly why I bought this switch — two 10G ports for my computer and NAS, with everything else on the 1G ports. Pretty standard home prosumer setup. The Problem Internet uploads are throttled to about 250-300 Mbps when my computer is on a 10G port. Downloads are fine at 830-880 Mbps. When I move the same computer to a 1G port with the exact same cable, uploads jump to 708 Mbps. That's more than double the speed on a port that's supposedly 10x slower. What I've Tested (at Netgear's request) I ran every test their L3 support team asked for. Here are the results: Internet Speed Tests (computer on 10G port 9): Flow Control Download Upload OFF 865 Mbps 306 Mbps ON (port 9 only) 879 Mbps 169 Mbps ON (both 9 & 10) 820 Mbps 137 Mbps Internet Speed Test — computer on 1G port (same cable, same everything): Download Upload 884 Mbps 708 Mbps iPerf3 between Mac and NAS (local, 10G ↔ 10G): Direction Speed Mac → NAS 3.73 Gbps NAS → Mac 9.40 Gbps Local 10G performance is excellent. The ports, cables, and NIC all work fine. What Netgear Says After all this testing, support came back and told me: This is "working as expected" and "within the design limitations of the switch" The 10G ports are "intended to be used as uplinks" — not for client devices A replacement would behave the same way My configuration is "not the intended use case" Why I'm Confused I don't understand how any of this is "expected behavior." Specifically: How does a 1G port give me faster uploads than a 10G port? If the 1G uplink is the bottleneck, moving to a slower port should give me equal or worse speeds. Not more than double. Nobody has explained this. Why are only uploads affected? Downloads through the 10G port hit 865 Mbps — nearly saturating the 1G uplink. The traffic crosses the same 10G/1G speed boundary in both directions. Why would only one direction have "buffer overflow" problems? Flow Control made things WORSE. They asked me to enable it. It dropped uploads from 306 Mbps to 137 Mbps. How is that a fix? The product page says "No Network Bottlenecks thanks to the 2 10-Gigabit/Multi-Gigabit Uplinks." Now support says those ports are only meant to be uplinks and my setup is unsupported. The user manual literally shows 10G client devices connected to ports 9 and 10 in its network diagrams. This switch used to work. I used the exact same setup with fiber in Chicago for years with no issues. I only noticed the problem after switching to fiber here in LA recently. Something changed. What I'm Asking Has anyone else seen this? Am I wrong to think a managed switch should be able to handle 10G devices sending traffic through a 1G uplink without losing 70% of the uplink's capacity? I've seen a couple other threads about similar issues with the GS110EMX and I'm starting to think this is a known design flaw that Netgear just doesn't want to acknowledge. At this point I just want to know if I should keep fighting for a replacement or just give up and buy a different switch. Any insight would be really appreciated. I've spent way too many hours on this already.
Advanced 802.1Q VLAN Doesn't Block Untagged Traffic?
I think the answer might be obvious. Lower-end Netgear switches are not managed using VLAN traffic, so they allow all untagged traffic to pass through. Is this correct? For example, a port is configured with VLAN ID 10 for untagged traffic and its PVID is 10. It will tag the traffic correctly and all the traffic will go to the correct subnet. However, if I manually configure my IP, I can access any other device on the link that is not VLAN aware. This could be another Netgear switch or a MoCA device. My configuration: Devices: GS308EP GS305E
