Hey so I have been having very annoying latency issues! It started yesterday morning. I tried playing a game (player unknown battlegrounds) and would repeatedly receive a "network lag" message which would happen every few seconds or so. I use a USB wifi adapter which has worked fine up until now (or it isn't the source of the issue). I also talk with my friends on discord and I noticed their voices would cut out in sync with these "network lag" messages and discord kindly shows you your latency which I noticed would go from 20 ms or below to crazy high numbers ranging from 2000-4000 ms. I have tried unplugging the USB wifi card several times and resetting the wifi module, the router in a whole, and my computer. None of these have worked.

 

I also normally get 60+ mbps download speed and 20+ mbps upload speed.

 

 

Below are a ping test and a tracert test to google.com (recommended by another thread on another site)

(I did multiple to show the latency as well. Side note, I was talking in discord w my friends while doing this and when the asterisk came up their voices would cut out for longer)
 
 
FYI: I keep editing this thread to add more information so hopefully someone smarter than I am in this area can piece together where this problem is coming from.
 
I noticed late last night and this morning (may 29) that I could see this issue on my phone as well in the same room as my desktop. The wifi indicator would go from 3 bars to 2 and repeated this indefinitely. I believe this rules out the possibility of my wifi card/adapter being the source of the problem. I also walked from the router to my bedroom (down a half flight of stairs and in the basement, I live in a split-level house) and found that near the bottom of the steps the spikes started to appear in the ping test I was running on my phone.
 
Also ran another ping test from my desktop:
 
Ping statistics for 10.0.0.1:
    Packets: Sent = 280, Received = 279, Lost = 1 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 2ms, Maximum = 697ms, Average = 10ms
 
It's less extreme but the spikes are still here. I turned off my old laptop which I had fired up yesterday (may 28) before I ran this test. Possibly had some kind of interference but issue is still present. Starting to think my laptop (2012 macbook pro) may have been causing some kind of interference. Either way if anyone has tips or a fix I am still in need.
 
Update (May 29 2pm) Ping got much worse now, I've been hitting 3000+ ping frequently now and it was going well until 5-10 minutes ago when my latency skyrocketed.

make sure you have ipv4 and ipv6 enabled in your tcp/ip properties of the nic.

 

run the netshell utility for fixing the tcp/ip stack [simple google search]

 

might be something wrong with nic or router with the 2300 ms ping of the gateway

Ok so I wasn't quite sure what you meant with the first one but I went to Device Manager > Network Adapters where I found the two adapters and dug around in properties of both. I found in the advanced section of the Intel® Ethernet Connection (2) 1219-V two properties called TCP Checksum Offload (IPv4) and another one for IPv6 which were both set to "Rx & Tx Enabled" so I assumed I was good there? In the other adapter (my usb wifi adapter) the advanced properties were less abundant and none had anything about TCP/IP or IPv4 or 6 so I left it be (most of the properties were set to enabled anyways). Also, before I saw this response I did a Network Reset which reinstalled these adapters and made sure the drivers were up to date which I could see in the "Events" section of the properties of both adapters.

 

Next, I entered (following steps from https://help.aol.com/articles/manually-reset-your-internet-protocol-tcp-ip-settings) "netsh int ip reset resetlog.txt" in the "type here to search" bar and clicked run. This opened a black window and I then restarted my computer. With no other knowledge the first thing I did was run a ping test and these were the results:

 

Ping statistics for 10.0.0.1:
    Packets: Sent = 126, Received = 126, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
    Minimum = 2ms, Maximum = 2293ms, Average = 26ms
 
I ran this test for a while and had one big spike up to 2293 and only a few other spikes in the 100s. Improvement? Either way not sure if these solutions helped because I am fairly confident it is a router issue. I have Xfinity wifi and the gateway allows me to restart the gateway, (no clue what this does) but you mentioned the 2300 ms ping of the gateway, should I try this out? Considering running ethernet cable if I can convince my dad to drill a few holes in the wall but not sure if this would help since from the trace route tests the spikes seem to come after the hop from my computer to the router (obviously would still help with internet speed but not to concerned about speed rn). So my question is, would ethernet help with this issue?

Hi

 

If you can try it with ethernet connection that would tell you if the problem lies with the wifi connection or if there is a problem in the internet providers equipment.

Perhaps the easiest way would be to move the computer temporarily into reach for ethernet cable connection.

is ipv6 and ipv4 checked? as in enabled?  You dug too deep :-) concerning the checksums.

 

You will note your tracerts were using ipv6 but ping was using ipv4.

 

another aspect of wifi is channel contention.  download xirrus wifi inspector and post a screen shot of what it sees for further recommendations

Channel interference might be the culprit.

Wifi is a shared medium meaning that when you talk everybody else on the same channel (or interfering channels) will have to be silent.
Much like a Walkie Talkie behaves.

It might be that your neighbor use the same channel as you and that you are affecting eachothers wifi experience

Hey guys, so I noticed these latency issues come and go in periods that could possibly be associated with when my neighbors are using their wifi the most. Also, I found the details of my adapter and both IPv4 and IPv6 say "Internet" next to them. I downloaded Xirrus Wi-fi Inspector and found it doesn't tell me much other than signal strength which is a consistent -71 dBm. I also found an option in the Xfinity gateway called WiFi spectrum analyzer Attached File  Wifi Spectrum Analyzer.PNG   57.99KB   1 downloads which shows all the neighboring networks and what channels they are on. I am on channel 1 which many of my neighbors are on as well. Not sure how to change what channel I'm on (if that's in my control) so if you guys think I should switch channels please also let me know how to change the channel (also read something about a router setting which auto-switches to the best channel, not sure if I have this setting?). Testing ethernet isn't a very viable option for me as I don't have an ethernet cord and I also have a pretty large desktop computer with no back panel so moving it isn't practical or safe. So seems like my best option would be to figure out this interference? Also since my signal strength is -71 would a range extender help? If it comes down to it, I might be able to convince my parents to run ethernet to my room but that would be the very last resort.

 

Also, thanks for your help so far and hopefully you guys can keep helping out

 

dug around in the Xfinity gateway and found my 2.4 gHz network is on automatic channel selection and is set to channel 1 with channel bandwith of 20 (instead of 20/40) I could change the channel selection to manual which would allow me to choose 1-11

Hello again

 

Please do NOT use 40mhz channel width on 2,4GHz band. It will interfere with all 3 channels than can coexist without interference.

Only channel 1,6 or 11

If I read the picture correctly you only see one other network on channel 11, is that right?
If so, I would choose this channel

Or if you get 5GHz equipment there will be a lot more non interfering channels making it easier to get good wifi signal

Your best bet though, would be to run an ethernet cable from the modem to your computer. That way you wouldnt depend on the wifi at all.
If you do gaming this is highly recommended!

 

Hth!

Ok awesome yeah we have 5.0 gHz but it doesn't quite reach my room. I'll switch us to channel 11 hopefully it'll work! Thanks for all the help!
