This can be confusing. There are $250 wifi routers that, when put in wifi bridge mode to be used as a switch, will not pass VLAN tags properly. Then there are $20 [https://www.netgear.com/business/wired/switches/unmanaged/gs308/ Netgear GS308v3 switches] that support VLAN tags perfectly.

You don’t have to spend a lot of money to get a switch that has VLAN tags. How do you tell if yours supports VLAN tags? Good question. Netgear’s [https://www.downloads.netgear.com/files/GDC/Unmanaged_Switches/300-Series_Gigabit_DS.pdf datasheet for the GS308] and their [https://www.downloads.netgear.com/files/GDC/GS308v3/GS305v3_GS308v3_IG_EN.pdf instructional manual for the GS308] do not mention the word “VLAN” - not even once. It says it supports 802.1p QOS, but that is not 802.1Q VLAN tagging.

Most modern switches DO support this; but what if you have an old one? What if you are re-purposing an old wifi router as a switch for this setup? Many wifi routers, even older ones, have settings that allow them to be used as a wireless bridge.

As I have said earlier on, when people tell you to ''“RTFM”'', what they are actually saying is ''“eat shit and die”'' - it’s their way of expressing that they hate you. Manuals are functionally useless for 99% of products sold, and rarely if ever answer actual questions. They answer questions that can be answered intuitively without a manual.

My best answer is as follows; if you are going to have a very small home network, the Netgear GS308 is a great pick that works with VLAN tags. It’s dirt cheap and a workhorse. If you want something that is more upscale, I’d suggest looking at the [https://www.tp-link.com/us/business-networking/omada-switch-l3-l2-managed/sg3218xp-m2/v1/ TP-Link Omada SG3218XP-M2] &amp; other switches in that series, for the following reasons:

'''2.5 GbE speeds'''

Most switches have gigabit ports. This means 1 gigabit - which translates to '''100-120 megabytes per second''' in the real world. Around 2009 when these started to become cheaper(sub-$200), this was more than enough, since hard drives of the time were in the 70-120 megabyte per second range. This meant that it made no sense to pay extra for a switch with more bandwidth, since your hardware was not capable of making use of the extra bandwidth. Whether using a $10,000 switch or the $50 1 gigabit switch, your transfer speed would be the same.

As time has moved on, even cheap desktop hard drives do over 180-250 megabytes per second, and cheapie solid state drives can achieve 200-400 megabyte per second read &amp; write easily. 1 gigabit ports on switches mean you are losing out on transfer speed.

2.5 GbE switches are capable of '''270-290''' megabytes per second,approximately, in the real world. This is still under the capability of more expensive NVME solid state drives, but it is over double what you get with the old gigabit switches.

'''Power over Ethernet(PoE)'''

If you do plan on setting up security cameras, PoE means that you can plug the ethernet cable into the camera without having to run a separate line for power. The power for the camera is provided by the switch through the ethernet cable.

'''Easy management using Omada controller software'''

If you want to have fun with some of this switch’s other features, you can use the same software we’ll be using for EAP-610 wireless access points to control the switch.
