[SOLVED] Insane spikes on my network

[Philip45645]

Hello. I currently have two routers in my house, the "primary" router which makes the connection with the ISP and a secondary router that repeats the signal of the router 1. For a while I've had issues with the router 2 because of the spikes affecting both my ping and my download & upload speeds.
Couple weeks ago I connected my main computer to the primary router through a broadband connection and ever since I haven't experienced any problems.
Meanwhile, my secondary computer is connected with broadband to the secondary router which, as I said, is repeating the signal of the main computer. Still, the spikes on my secondary computer are annoying, usually my ping is between 1 and 2, speeds are 100 download/100 upload, though on the secondary computer the ping goes from 15 to even maybe 200 and the speeds go down to 10. I haven't found any problem with the router itself so I want to know if this is something that I can fix through some settings or if I should consider buying another router.
Also I'd like to mention that these spikes were happening on multiple devices so I doubt it could be an issue with my second computer.

When you say "broadband connection", you mean Cable connection ?

Have you had this issue from the beginning (i.e. as long as you have had this excact setup) ?

What brand and models are your routers?

How are the routers connected to each other? Cable or WiFi ?

Yes, by broadband I mean cable connection. I haven't had this problem from the beginning, it started a few months ago.
Both routers are TP-LINK TL-WR841N and they are connected through WiFi

Can you remember any changes to the network equipment made in the time before you noticed the problem? Any devices added to the network? New neighbors that having powerful routers moved in next by?

No.

Why do you have the second router. Can your PC not connect via wifi to the main router. Where did you physically place the second router in relationship to your pc and the main router.

It sounds like you now have 2 wifi signals in the path between your computer and the main router. Either or both of these could be getting errors causing the ping spikes.
