I'm currently on a 200/20 plan. I've noticed lately that after being connected to UFB for a while, the speed drops down to around 45/20 for some reason. I usually notice it when downloading something off steam or a well seeded linux torrent, because they seem to max out at around 5-6 MB/s while when things are running as they should, I usually hit 20+ MB/s especially in Steam. If I stop the download and run a speedtest at this point it also comes back at around 45/20:

If I then restart my Frtizbox the speedtest then bumps back up to expected speeds, and more importantly steam downloads run at full speed...

I suspect it's something to do with the Fritzbox, since a restart of it and only it seems to fix the issue. Anybody seen anything like this before or have any ideas?

Next time it goes slow. Run a speed test and at the same time browse the admin Web pages on the fritz box. Do they take ages to load? If so then the processor is getting overloaded.

OK, it's doing it already. I'm guessing it pretty much does it daily, it's just that I only notice it if I have a large download. The fritzbox admin screen loads pretty much instantaneously and login is also pretty much instantaneous, along with navigating from page to page on the fritzbox interface, so it doesn't look like the processor is overloaded. Under energy monitor -> CPU usage, there are occasional spikes on the graph, but only up to about 15-20% and the majority of the time it looks like it's under 2 or 3%.

The only thing of note is that I tried it a few times this morning and it seemed fine, but some time this afternoon it dropped down... and there's the following message in the event log:

"13.03.16 12:28:28 The service provider successfully transmitted settings to this device."

That message happens every day. It does not mean that 2D has changed any settings, just that a daily check has been done between the settings on your FritzBox and the settings in 2D's database. If they were sending out new settings, you would still see the same message, but it pretty rare for them to change things.

What drives the timing of that daily check? Today it shows up in my fritzbox event log at 10:28 and when I just checked my connection is stuck back at 45 megabits down. I'm sure it is unrelated, but currently it's the only thing I can see that corresponds roughly to when the connection speed drops.

I do not know how the timing of the daily check is done, but I suspect that it is initiated by the FritzBox. On my 7390, it happens about 2 hours earilier every day, so it looks like the FritzBox is just doing it every 22 hours. It is very unlikely that it has anything to do with your speed drop, as it is unlikely that any settings are being changed. You can easily find out though - just do a backup of the FritzBox settings and save it without a password. That produces a ".export" file, which is in text format, so you can then take another backup after the next settings update and do a diff to see if anything has changed.

I'm sure you're right, but anybody have any ideas on what else I can look at to try and diagnose? The fritzbox is not showing any traffic or significant activity when this happens...

Tried updating firmware on the router to see if it fixes the issue?

Do whatever you want to do man.

Good thought, I'll check what I'm on tonight - I think it's 6.30 - I updated it somewhat recently when someone linked on these forums to reports of a possible exploit, I think within the last 4-5 months.

Any chance the FritzBox is overheating? You can check temperature history in the System-Energy Monitor-Statistics tab. Could be the fibre interface box that's the problem - but I don't know how you'd check that without making sure that it stays cool.

Ethernet or WiFi? Is the green option enabled (that is, takinkg the speed on ethernet ports down to 100Mpbs instead of 1Gbps)?

This is still happening on a daily basis. Fritzbox temperature graphs look absolutely fine. It's not the green setting either - that was one of the first thing I checked, they're all set to "Power mode" And yeah it's all wired not Wifi.

Restarting the fritzbox always fixes it immediately, but I've also found that restarting (powering off and on) the gigE switch that sits between my desktop and the fritzbox also fixes it!? So now I'm wondering if that's the problem... It's a tplink switch that has seemed rock solid until now... I thought they were pretty "dumb" and didn't have much to do much. It's not getting hot to the touch or anything. Is it possible some sort of green mode is kicking in on the switch though??

I'm also confused as to why rebooting either the switch OR fritzbox fixes it (rebooting my desktop doesn't - my home server is also plugged into that switch and rebooting it also doesn't help either)

do you have a different router you could try?

Jase2985:

I have my old fritzbox, but it only has 2 ports, and I need 3 lol.

Looks like something is dropping the switch to 100Mb/s (it's plugged into LAN 3 with my desktop and home server plugged into the switch - I swapped it from LAN4 last night to see if that would make a difference but nope.)

Sure it has less ports but if you want to find out a problem in your network you will have to do it.

Yeah, was just hoping someone might have more suggestions before I had to do that. I've swapped the the 7490 for my old 7340. Time to wait and see now...
