ORBI RBR50v2 slow connection to work VPN
Currently I have an ORBI 52 + 2 satellites connected to FTTB via an open reach Nokia modem. The connection is as fast as expected on all devices at approx 450mbps. However, when my laptop is co...
1. Can you please provide the latency time for when connected via Orbi vs when you are connected directly to the modem
2. Can you please also make trace route comparison for both cases.
3. Few VPN providers detect when you’re connected via a router (using ttl or MAC address) and think that you’re sharing the connection and therefore limit the speed. Can it be that your VPN provider is doing that?
To test this you can test to set the MAC address of your PC as the MAC address of Orbi in the Orbi internet settings and see if that helps (if ttl count is used then this won’t help).

Another important aspect with VPN is fragmentation and packet sizes. The MTU size setting in Orbi might affect this.
You can check with your work IT on the type of VPN being used and the fragmentation requirements, but I would recommend that you change your MTU size to a max of 1460.
Please see this Netgear KB article for reference: https://kb.netgear.com/25675/How-do-I-change-the-MTU-size-on-my-NETGEAR-Wireless-Router-DSL-Gateway
Thanks for the suggestions, I have played around with the MTU, ranging from 1430-1500 and the download speed doesn't change much, however the upload speed increases the higher the MTU is.
The ISP router which connects to the work VPN with no issues has an MTU of 1500.
I have also tried changing the MAC address of the router to match the PC but it didn't improve the connection.
Do you have any other ideas please?
I'm not sure how to test and make a trace route comparison of the latency but will try searching for a tutorial.
- You mentioned the ISP router in the last post, this is not connected to the network when you have Orbi connected, right? 🙂
