Model: Archer VR2100  
Hardware Version: V1
Firmware Version: 1.5.0 0.9.1 v009e.0 Build 210619 Rel.63114n

When NAS and PC connected directly point-to-point (without any router) with ethernet cable I achieve almost gigabit speeds (900Mbit or 112MB/s). When Archer VR2100 is connected between them acting as router (with the same ethernet cables), I can only achieve ~560Mbit (or ~70MB/s), sometimes only 40MB/s. I'am little bit disappointed, copying takes 2x longer . 

 

 

PS: When i enable QOS (without any rules), then ethernet local LAN speed is maximum 20MB/s .

Can someone measure maximum LAN ethernet speeds on their VR2100 ?

This is ridiculous, year 2021 and router is not capable to transfer 1gbit LAN.

Hi

May I know how do you access the NAS on the local PC, via IP address of NAS or domain name?

Later I would like to forward your case to the senior engineers and could you please post all the speed test pictures to me?

Since QoS did not help, please keep it off.

Thank you very much.

hi, using IP address to access NAS, copying from NAS to PC, in pictures I renamed file to be sure it is not cached.

 

 

picture 1
router uptime 2 days, internet connected, ethernet cables length 10 meters)

 

picture 2
direct connection PC-NAS (with same ethernet cable as in case 1)

 

picture 3

router freshly rebooted, internet disconnected, different ethernet cables length 2 meters)

 

picture 4
router freshly rebooted, internet connected, ethernet cables length 10 meters (same cables as in case 1)

 

picture 5

same as 4), copying different direction : from PC to NAS

 

UPDATE : I did factory reset on router and now I'am getting gigabit speeds (112MB/s) from the Archer. Very weird LOL. I will monitor if speeds are now stable or degrade again, will let you know.

 

My opinion on what happened : when I first setup router I enabled QOS for the NAS (low priority for the NAS IP address). I did not test LAN speeds, but probably they were already half - around 50MB/s. Then I updated firmware to current version (beta). Then I noticed very slow LAN speeds 20MB/s. Then I tried various configuration options in web setup, I disabled QOS - and speeds were back to 50-70MB/s, which is still not 1000mbit. So my conclusion is : that somehow QOS stayied enabled even after I disabled it router web configuration (maybe during firmware update process?). And when I tried to enabe them again, they were applied twice (that was the very slow 20MB/s speed when QOS was enabled). Just my opinion.
