TF2 Lag Spikes

[Sheldon Serdadu]

A few days ago I replaced the router in my house and from then I beginned to have Lag Spikes (lag spikes are that sometimes youre stuck in place, everyone else are moving and fighting but you're stuck in place and then you go back to where you've been a few seconds before the lag spike begun).
I've tried deleting all files in the steam folder except steam.exe userdata and steamapps, I've verified the cache 10 times and none of it helped. Someone please help I like TF2 and I dont want to stop playing cause of those stupid lag spikes.
