T1600G-52PS Slow Throughput / Internet?
I just put in a new T1600G-52PS v4 switch and it has significantly slowed down my download speed. I have 1 gig internet speed and when I do a speed test I consistently get roughly 300 Mbit down. Sometimes it bursts to 500-ish Mbit right as the test starts but very quickly slows down to 300 Mbit or less, often even down to 200 Mbit. If I bypass the switch and plug directly into the EdgeRouter X I consistently get 800 - 950 Mbit on the speed test. I thought it was something with the switch but I get the exact same results if I replace the T1600G-52PS with a T1600G-28PS. These are brand new switches on the latest firmware version and with virtually nothing configured other than a static route for 0.0.0.0/0. Bandwidth throttling isn't enabled, this is truly a vanilla install. I tried messing with QoS but no luck there, these are also brand new Cat 6 cables. I've tried different ports etc. Any ideas?
My Configuration
PC > CAT6 Cable > CAT6 Patch Panel > CAT6 Cable > TP-Link Switch (T1600G-52PS) > CAT6 Cable > Ubiquiti EdgeRouter X > CAT6 Cable > Cable Modem
Thanks,
