First post, I'll try to be brief but will try to include as much info as is relevant.
My son is an avid gamer (Smite) but is getting disconnected from the server 3/4 times a day resulting in ever increasing time bans. There are a ton of things to tweak on his PC (which I have tried) but to no avail. One suggested test was to run two continuous ping tests on two PC's to see if they both hiccupped at the same time when he gets disconnected. This would rule out his PC being the problem and point the finger further up the line. Sure enough, that's what we saw. We were both pinging the router (and google) and the constant 1ms pings jumped to 33.
I continued to run the -t ping test for several hours. 11 times I scrolled back through the last minute and 11 times I saw spikes usually between 30 and 50ms but once to 342ms and ten seconds later 505ms. We phoned the ISP, they ran a test for 24 hours but found nothing. They said they were going to run another 24 hour test but before we could finish the conversation, I was placed on hold and then cut off. This was yesterday.
They want €50 if they replace the router and find it to be fine and I'm hesitant to get them to replace it because for me, it IS fine. I don't notice these hiccups but my son does but they don't always result in a disconnection or he would be disconnecting every minute.
So now I ask myself, are the two related or was it just a coincidence that we saw a spike in the ping at the same time of his disconnection? Are ping spikes normal and nothing to be concerned about or is the router faulty? (no router firmware updates available)
I'm no expert, just a dad with some knowledge learnt over the years but I know my limits (usually when google can't help me, which isn't very often).
A bit more info, 300mb fibre optic line and my Sons PC (which shows 300mb up and down on speed tests) is 3 years old and was top spec at the time of buying and is connected by RJ45 cable.
Any help on the ping hiccups or connection issues greatly appreciated.
