Nighthawk X4S C7800 - Random Lag/Disconnectivity

Question

I'm experiencing very consistent lag spikes with this router. I have 1GB internet through Comcast. I ran several speed tests and the internet speeds aren't the issue. I've tried rebooting the router, factory resetting, rebooting through my ISP and I'm still continuously getting these random lag spikes while gaming.

There are not other devices connected aside from my laptop and mobile phone which aren't running anything. I can't seem to figure out why this consistently keeps happening and quite frankly I paid way too much to be having this issue.

Can anyone point me in the right direction as far as troubleshooting or potentially a solution to the problem?

Is it a specific game thats having the issue or all of the games?

Is it a gaming platform like ps4, xbox, or is it a pc?

How is it connected? Wireless, wired

do you have a snap shot of your modem connections page? I've seen connections be boarderline and work for the most part and then randomly cutout due to the boarderline connection.

Any sketchy, loose, corroded connections? These can cause random drops. As can kinked lines, moisture within the cable, or even low quality coax cables. Try removing any splitters, amplifiers, 90 degree elbows that might be in the line.

Hi Plemans,&nbsp;I've only been playing one game at the time I was experiencing the random lag spikes on the PS4 (Wired). However, I confirmed with multiple people at the time and no one else was also experiencing the connection issues and I could also confirm that it was only me through my choppy voice chat audio in game chat.&nbsp;Can you clarify as to what you mean by the modem connections page?&nbsp;I can confirm that it's not the connections as the complete drop in connection happens on all devices. I had it happen on both my wired laptop and the PS4. There was a splitter in before I had the 1GB internet installed but it was removed upon install months back before I began experiencing these issues.

this is how you get the cable connections page. it'll show signal strengths/errors/etc. Take a screen snip of this (get the whole page, even if you need multiple snips) and post it here. It shows a brief snap shot of your connections link.

Are there any other splitters, connectors, ampliefiers in line? How far is your cable run from where it enters your house to where the modem is?

The XFINITY cable box is just outside my window, so I'd say the cable running to the XFINITY cable box is about 3 yards, and then the cable from the XFINITY cable box to the cable box with everyone elses cable lines is about another ~5 yards. So as far as distance, it's not far at all.&nbsp;I also had a technician from XFINITY recently come out to do an inspection of the lines, we found a few kinks in the outside line so he changed that and put in a brand new line outside and also switched the line inside to the old cable line I had previously running to my TV (just to clarify, there is currently no splitter connected, this was just an extra cable cord I had sitting in my room.)&nbsp;The issues are still persisting, I'll restart my router I'll see a healthy connection at the speeds I should normally be getting then it rapidly dips down to drastically low speeds.Current System Time:&nbsp;Thu, Oct 31, 2019 01:23:39
