nph84 Posted August 19, 2021 Share Posted August 19, 2021 Hi, all I have been using the Netgear XR1000 with the DumaOS for a while now, and while everything is working great on the gaming and QOS side I have been stumped with some major wifi issues. I recently replaced a couple desktop wifi cards to wifi-6 (Intel AX200) and before I replaced the cards my transfer speeds between computers were around 29mb/s. Now I can't get above 11. We not too long ago had a couple of laptops that got about over 100mb/s transfer speed over wifi with wifi-6 this is what inspired me to do the switch in the first place. After messing with some wifi adapter settings and some channel settings on the router page I was able to get 75mb/s on one desktop, but it didn't last long. I was just wondering if someone could provide some insight as to why I am getting such low transfer speeds when I know the equipment is capable of much more. As of right now after resetting the network on all computers I am getting 11mb/s transfer speeds even on the new laptop. If nothing else I would like to know what settings influence wifi transfer speed between computers. I tested the wired speed and it is around 110 mb/s, so that's fine.

Netduma Liam Posted August 19, 2021 Share Posted August 19, 2021 It could be QoS limiting bandwidth, try fully disabling QoS from the three-line menu in Congestion Control and then re-test speeds. Link to comment Share on other sites More sharing options...
nph84 Posted August 19, 2021 Author Share Posted August 19, 2021 Disabled the QoS, this unfortunately didn't fix the issue. Thanks for the suggestion though. Link to comment Share on other sites More sharing options...
Netduma Liam Posted August 19, 2021 Share Posted August 19, 2021 Thanks for trying! Did you have to re-connect the PCs after replacing the Wi-Fi cards? It may be worth disconnecting them, removing them from Device Manager in DumaOS and then re-connecting them, perhaps the XR1000 isn't recognising them as Wi-Fi 6 compatible devices yet.

nph84 Posted August 19, 2021 Author Share Posted August 19, 2021 I was looking at things and realized the main cable from my switch to the router in the main room had an orange light so I unplugged and plugged in the ethernet cable now the light is green. Now I am getting 24mb/s. Just trying to figure out how to get back to those amazing wifi transfer speeds I was experiencing. Have 2 desktops and a laptop. Laptop was getting 110mb/s, desktop was getting same, desktop 2 was getting 80 Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 19, 2021 Administrators Share Posted August 19, 2021 Are all the devices connected to the XR or are some connected up/downstream? Link to comment Share on other sites More sharing options...
nph84 Posted August 19, 2021 Author Share Posted August 19, 2021 One desktop, ps4, and a TV is connected via ethernet. The rest is wireless , mostly on the 5Ghz band. Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 19, 2021 Administrators Share Posted August 19, 2021 Have a look on the network monitor when you're doing a transfer, are you seeing any other devices using bandwidth at all? Do you have any wireless/electrical devices within close proximity to the router? Link to comment Share on other sites More sharing options...
Bert Posted August 19, 2021 Share Posted August 19, 2021 How are you testing this file transfer? One thing that is new in Windows nowadays is write back caching. So when you transfer a file, it goes to windows memory at full speed and then slowly gets written onto the target device. One thing is that most external devices do not use write back caching. Other thing is that when you are copying files and you inmediately try to copy them back, the file isn't fully written to the drive yet resulting in very slow transfers. Another thing is that write back cache in win 10 is limited to 1GB. So if you exceed that the transfer will slow down. What I would actually suggest is using iPerf3. Use it on both clients and then test bandwidth. Preferrably, run it on your wired PC as server and use the wifi devices as client.

nph84 Posted August 19, 2021 Author Share Posted August 19, 2021 Reconnection of the PC's was not an issue, I not too long ago had the appropriate speeds just trying to get them back. When I do a file transfer the network monitor doesn't pick anything up. There is a television near the router, that is all. I'm testing this transfer in Windows 10. The transfers were done between 3 different computers. Using windows file transfer I was able to achieve the proper speeds. It shouldn't be so difficult to attain these speeds again, but here we are... Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 19, 2021 Administrators Share Posted August 19, 2021 For 5GHz on the XR, drop the speed down from the Up to 4330 Mbps option to the Up to 2165 Mbps option and see if it is any better Link to comment Share on other sites More sharing options...
nph84 Posted August 19, 2021 Author Share Posted August 19, 2021 My respective speeds are 4800 and 2400 so I'll go ahead and adjust to that. Link to comment Share on other sites More sharing options...
nph84 Posted August 19, 2021 Author Share Posted August 19, 2021 Tried it and the speed went down from 25mb/s to 20mb/s Link to comment Share on other sites More sharing options...
Administrators Netduma Fraser Posted August 19, 2021 Administrators Share Posted August 19, 2021 Shouldn't have really made much of a difference there, I'd suggest making a ticket directly with Netgear as this is more of a hardware/NG settings issue and they're more likely to have some suggestions for you to try Link to comment Share on other sites More sharing options...
