Yes, my bad. It is indeed the telco line, I'll try that tomorrow and see how it goes.
Alright, I've now set it up just like you said. Disabled DHCP and connected the modem to the router's LAN1 port (1 of 4). The connection seems to work in any way I try it, but the main problem remains the same. My ping is almost always above 600 which makes it impossible to play any online game, or to watch video's, streams, youtube music, anything.
It just seems like there is too little of a bandwidth to work with in the first place. The problem with that is that in weekends or at night (past midnight) or in the morning (before 08:30) speedtest gives me 16Mbit/s to work with. In the afternoon it peaks at not even 2Mbit/s.
Do you have any Idea at all what could cause this? Because I'm starting to doubt it's the router/modem and starting to blame the ISP for this mess because literally every combination works but has sky-high ping.
Edit: To make things worse, in the first ~30 seconds after a complete router restart, the internet connection has 30 ping and ~16Mbit/s. After those first 30 seconds, it goes back to 600+ ping and max 2Mbit/s. How? What? I... Huh?
this was meant to imply your concern
I see what you mean now...
I just read on the internet that some other customers with the same ISP have had similar issues, extremely low download speeds etc. They were told by a professional to remove 'some kind of white wire' from the incoming connection (ie: what comes in the house from externally) and that that solved all their issues. I was hoping this could work for me too, but I'm unsure what wire they're talking about. Do you have any idea?
Sorry there mate - - I believe that's referring to the telco line itself and that is very specific to your locale.
you need to get a 'pin-out' diagram of the telephone wiring to proceed on this approach.
If you elect to proceed, dismount the wall plate where the ZyXEL is wired and you should see screws holding
the wires to the backside of the plate. If so, you can non-distructively disconnect, test and if necessary reconnect.
Ok, decided to do it the hard way and connected the modem to my laptop with my laptop balancing on the shelf
Re-configured the modem from there, nothing seemed out of place. Came up with the idea to run some "ping -t google.com" from there, turns out my ping was a constant 25ms or lower, with my internet speed approaching a constant 16Mbit. Meanwhile, the connection from the router's wireless remained to be around 4Mbit/s at max, with ~500 ping.
In my eyes this is conclusive evidence that the router is bad, and I'll replace it this sunday.
I have a similar problem im using an ethernet cable to connect my labtop to my modem and im getting over 300 ping but 2 weeks ago it used to be 66 ping can any one help
