This router uses a 4G mobile phone uplink --- it is wireless both towards me (wlan) and towards the ISP (4G). There is no cable as such. Somewhere in the nearby there is a telecommunications radio antenna which provides coverage for my neighborhood --- for internet connections, mobile phones, HDTV, and so on... It is possible that some of that equipment might be broken, but I doubt that it is working beyond its design capacity so badly that it cannot provide me with my 20Mbps. > Perhaps you would get better download speeds from remote to local > if you tried it after local midnight. Well, if I ma paying for 20Mbps download link, I expect to get 20Mbps throughput at any time of day. The ISP also offers 40Mbps and 100Mbps (for extra money), so I doubt that they are congested that much. > If it "used to be" 20 Mbps, perhaps a new user has come online on > your cable segment. It is possible that the network is more congested during the day, but if that were the case, I believe that my ISP would have a whole line of people complaining all over the city... :-) > > To test the local link, I opened 15-20 random youtube links > > simultaneously in Firefox.

Yes, that seems to be the case, and yes, it appears to indeed make a difference. On further inspection, it looks like I can indeed get the full 20Mbps "in total", but every particular connection appears to be capped at either 2Mbps or 150Kbps. And that is very broken. I have even tried to do a yum update, and it connects to a mirror at 15KBps (150Kbps)... The question really is the following --- can that be a local effect of something in Fedora, or my router, or is it down to the ISP? I would test it with a LiveCD if I had one, but I don't and it will take forever to download any iso... :-( If all else fails, I'll contact my ISP (and work my way through their seven-gates-of-hell "customer support" thing...), and hope they can do something about it. Anyway, thanks for the thoughts!
