Having just moved house, I noticed the wifi in my study was patchy. I therefore invested in a TP Link Powerline (TL-WPA4220) to run from my router to my study.
It works perfectly on all my personal devices (Windows, Apple, Android etc) with them all getting the full wifi speeds promised by my ISP (Vodafone), both over wifi and ethernet.
The main reason I installed this, however, was for a fast reliable connection to my work computer. But whether via wifi or ethernet I'm getting much slower speeds on my work laptop than my personal devices connected to the same powerline - even slower than before I installed it when I was working at the far edge of my router's range. I'll be getting 70mbps download and 25mbps upload speeds on my personal devices and 2mbps download and 5mbps upload on my work computer.
I called my work IT, they suggested my ISP was throttling my use (when testing the connection on my work laptop we found that when I connected to my ISPs network / server the speed was as expected, but any other server was very slugglish, which led them to think this).
I contacted by ISP who insist they're not throttling my use and it must be something to do with my employer's IT policy. They did give me a static IP address suggesting this might help (but it hasn't).
Any ideas why this might be happening?My main suspicoion is that it's something to do with the VPN on my work laptop (zscaler), although when I tried installing a VPN on my own persional laptop it had no effect on speeds. How could my laptop / VPN even recognise that my internet is coming from a different source? Are there any known issues with powerlines accessing secure VPN networks?
I'm being bounced around to different people none of whom have a clue, so any advice would be gratefully received!
Hi all, as the title suggests I am getting awful internet speeds while using my powerline adapters. I have been quoted upto 500Mbps and when I do a speedtest from the router, I get around 450Mbps ish. When I use my computer which is upstairs over the powerline, I hit roughly 20-40Mbps. Wireless I get a bit better around 200ish depending on the device. The reason why I want to use wired, is because there are too many devices on wifi and I would like to use a lot more bandwidth while streaming or gaming.
My question is, what could be the cause of this? I have tried different plugs and cables but no change. Any suggestions on what else I could try? The powerline adapters that I am using are TP-link model number:TP-PA511
I haven't touched my network setup in a long time as it's been working with no issues for months.
Over the last week or so, I've noticed that some devices struggle to stay connected to the network. At the moment, there's a Kindle and a desktop that are struggling to stay connected.
I've no idea where to start looking into this so any pointers would be great!
I have a USG, two Unifi APs (Lite) and a D-Link switch (DGS-1100-08P).
