Hi everyone,
I’m having issues with my NAS setup, which I use to allow video editors to access files remotely. I’d really appreciate any help or suggestions.
My setup:
- NAS: Synology DS1621+ with 3 x 8TB Seagate IronWolf Pro (RAID 5)
- Router: TP-Link Archer A8 (Gigabit only)
- Switch: TP-Link TL-SG108E (Gigabit, supports LAG)
- LAN setup:
- NAS is connected to the switch using 2x LAN cables with LAG configured.
- Two PCs are connected to the switch via LAN.
- One PC is connected directly to the NAS (LAN) and to the router via Wi-Fi.
- One laptop is connected via Wi-Fi to the router and accesses the NAS remotely.
Remote access setup:
- I’m using Tailscale to enable remote access to the NAS.
- I forced peer-to-peer connections using port 41641 (as recommended online).
- Editors mapped the shared folders via SMB, and connections show as peer-to-peer in Tailscale.
The problem:
- Local LAN speed is as expected (~100MB/s).
- Remote download speeds are extremely slow — downloading a 5GB file takes 7 hours.
- If I bypass the external switch and connect everything directly via the router, it’s slightly better (5GB downloads in ~4 hours), but still far too slow.
- The peer-to-peer connection seems established, so I’m unsure why the transfer speed is this poor.
What I suspect:
- It may be due to the upload limitations of my router or ISP, but I’m not sure, on any network speed tests is almost 1GbE download and upload.
- I’m considering upgrading the router, but my budget is limited.
Upgrade options I’m considering:
- ASUS RT-BE92U
- ASUS RT-BE86U
- Ubiquiti UCG-Fiber (30W) – probably the best, but well over my budget
Questions:
- What could be causing such low download speeds even with peer-to-peer set up in Tailscale?
- Would upgrading my router improve remote transfer speeds significantly?
- Between the router options listed above, which would make the most sense in my situation?
