There is a technician coming to check out the internet box next week, so if it's a cable or something, we'll find out. a) IB GUI = Internet Box GUI? I will check when I am home next, but note that I do get the same DL/UL speed when plugged in by LAN to my internet box. b) I didn't include a screenshot to avoid cluttering the page, but the Swisscom home app measures the same speeds. My last test measured 2.13 Mbit/s DL and 0.09 MBit/s UL.
I have a Internet box plus, with a Swisscom Internet S package. I'm not expecting our speed to be impressive, but I should have up to 40 Mbit/s (5MB/s) download/upload speed, and our neighbourhood is supported for 1Gbit/s speeds according to the Swisscom address checker. Running the Swisscom internet test, as well as dslreports.com's speedtest, I get the following results: Swisscom: DL = ~2.13Mbit/s, UL = ~0.1Mbit/s dslreports summary of multiple tests: Bizarrely, I get the same results when connected to the router by LAN (Fiber) or WiFi. So my network connection is great. Our upload speed is a problem though: video calls and online games constantly drop out. I have manually updated the router's firmware to the latest version and rebooted the router, with no improvement. As mentioned, I have also tested the connection via LAN and WiFi (on a macbook pro), and I get the same results with our Nintendo Switch (WiFi). Any suggestions?
