Packet Loss issues
Hello, I have been living in myapartment building for almost 2 years now and I have been having horrible and inconsistent packet loss. The inconsistency has made it hard for me to get a tech to find any issues. I have had a tech come out twice now and report speeds are just fine. My issue however is not my speed. It is my high amount of packet loss. My setup: Modem: Arris SB8200 Router: Netgear Nighthawk XR500 All devices are brand new and have been replaced. Below are some tests done on ping plotter directly connected to mymodem. All tests are wired. Packet loss connected directly to a modem: https://imgur.com/a/6L6M0ZX https://imgur.com/P13w4B1 https://imgur.com/7G2cP5H https://imgur.com/fM8z15D https://imgur.com/EjDVRDt Here is a simple ping to google from my terminal: https://imgur.com/eGiYKE7 Can anyone advise on what to do next? I am not sure how I can show this to a tech because whenever they come out they tell me my speeds are fine.
Insanely bad ping spikes.
This is what my ping looks like throughout the day with Cox "Gigablast". As you can see this is anything but gigablast. My ping will constantly spike like this throughout the day. Sometimes it goes away after 2 am but I'm not trying to play games after 2am. There has to be some kind of explanation to this. Honestly if Icould switch ISP's I would. It's horrendous. I don't even want to play my games or watch a stream because of how unstable the internet is. I will be trying to get a tech to my house soon but over the last couple of months it has been getting worse and worse. https://imgur.com/a/U1hMrOn
High Ping (Cox Gigablast, Wired)
Hello, For the past 2 months my ping has been averagely between 75 - 120 with huge spikes between. My connection was fine before . I've been trying different ways to improve it with no success. For Example: New ethernet wire, different combinations within Cox App, checking comp firewalls, VPN, checking comp for network hogs. I got Cox for gaming and it was great but now it is a lag fest online.
Intermittent Latency
Has anyone else also experienced extreme packet loss and huge latency spikes over the last 8 months? I have put in a total of 17 tickets with Cox at this point and its the same exact story every time where someone comes to my house looks at the cables and tells me there is nothing wrong physically. I tell and show them all of the packet statistics i have captured over the last many months. They then tell me they will give me a call after talking to their engineers and I never get that call. Here I am at 9:00 PM still having issues after providing more proof than any customer should have ever provided. I know for 100% sure the issue lies on whatever the first hop is from my modem to whateverrouterthat it connects to. This is not a physical problem it is the equipment that cannot hold up to the bandwidth that is being pushed through it. I do not want anyone coming to my house again I just need a network engineer to please at least address this issue for me. If anyone has any guidance that has also went through this please let me know.
Random packet loss started after a bad night
Hello everyone, I have always used the gigablast plan without any issued until a few days ago (9/20/2020), when my internet speeds were sub 1mbps and I just figured cox must have been doing some work. Whatever it happens. The next day everything seems fine and without any issues (speed test looked good), however I start noticing that at very random times, I will have some packet loss no matter what I am connected to (Rocket League, World of Warcraft, League of Legends, discord etc.) All the wiring is very new, everything checks out signal wise on the modem and there are no major events/issued logged. I suspect that whatever was being done to a box perhaps was not fixed. This has been going on for 3 or 4 days at this point and the issue appears at all times of day An example node to look into is the following: 68.1.4.252 - This one is owned by cox Location: Gilbert, AZ Logs since the issue started (note that on 9/20 which is when my internet was terrible, there were tons of errors): Current levels on modem: Current Downstream (pt1), ends at channel ID 24: Current Downstream pt2 and upstream:
Crazy Lag and Packet Loss
Hoping to get more help here than I did with Cox customer support. I have had this ISP for about 2 months now and my connection has been horrible. Things load fine on wifi for the most part butanytime I am hardwired into my router, I have horrible packet loss. This makes gaming a huge pain in the **** and I have tried almost everything I can think of to fix it but nothing changes. Now, Xbox live and the games I play like to report that I am getting maybe about 1% packet loss but the gameplay is much much worse than just 1%. Even when I hardwire my computer into the router and run a ping test, it shows about 15-20% packet loss. Does anyone have any suggestions that I should try? Here is a list of things I have already tried: Used Cox provided modem/router: terrible packet loss on ethernet and wifi (mostly ethernet) Modem isfor sureplugged into the coax port very securely Changed ethernet ports:issue still persists Set up Xbox live port forwarding:issue still persists Setup QoS:issue still persists Tried entirely new ethernet cables:issue still persists Tried gaming on wifi:issue still persists (and I am not a heathen) Factory reset modem/router:issue still persists Switched the provided router/modem combo intobridge modeso it only acts like a modem I am now using my TP-Link AC1750 router:still terrible packet loss on wifi and ethernet (mostly ethernet) Set up QoS rules for bandwidth:issue still persists Setup port forwarding:issue still persists Reset xbox:issue still persists Manually set IP and DNS:issue still persists I have also ran a bunch of traceroute tests as well as ping tests to show where it appears to be slowing down and losing the packets. You can see all of these tests in the folder linked here: https://drive.google.com/drive/folders/1i59D5DTk2O7UvL0WBrqJYVITDr305hvT?usp=sharing All the slowdowns and packet losses appear to happenoutside of my network. It looks like it hits slowdowns when it is out in Cox's servers bouncing around. Is there anything that I can do to fix this? It looks like there is an issue with resolution of domains. My traceroutes to 8.8.8.8 show an unusual amount of dropped packets and lag at certain servers. PLEASE HELP!!Network spikes
Over 200 spikes in under 2 hours. Games are unplayable. This is wired with no one else using the connection on the 500mbps plan with your Cox panoramic router. It's not the cables. Even with the elite gamer software things are horrendous. Is there any hope before I switch to CenturyLink? https://imgur.com/xwq46yL
Been having horrible packet loss, low speeds, and high latency
For the last what feels like 6 months, I've been getting worse and worse performance from my internet, with no end in sight. I often online game, and with the network stats that I get, its been getting less and less playable. I had a tech come out to see and they fixed one of my cables, but it didn't seem to fix anything. I was wondering if anyone could look at my logs and my modem stats to maybe give me a starting point to what could be the problem. Thanks in advance to anyone that might could help. My starting freq. is405000000. And I'm using a CM1000.

Its back!! Hopefully Becky is still here in the forums. Im getting constant packet loss at hop 2.
Any moderators that could look in to this would be great. The loss % will be anywhere from 2% to 35% and it is constant. I spoke with an agent on the app messaging but he said he had no idea what to do and asked if I could get back to Cox later. So here I am, again, hopefully someone can get this fixed. Im not sure if hop 2 is my home network or coxs once it leaves my house.Extreme packet loss while gaming/voip (San Diego, CA)
I would to post here before resorting to filing a complaint to the FCC, for the past few months now I've been experiencing extreme outbound packet loss while gaming. I've had no issues until a couple months ago, the packet loss was a small 4% while playing Fortnite. It has then since gotten much worse as now I get packet loss and stuttering in any game that I play online, even just being in a discord channel Iget really bad connection quality and spiking. I've reformatted my hard drive, re-booted my modem countless times, I've always have had a wired connection, changed the coaxial cable that came with the router, changed the Ethernet cable that came with the router, upgraded the internet speed, tried almost everything to fix the problem and nothing has been helping. Every single game that I play that is multiplayer is affected by this packet loss and stuttering. https://imgur.com/rj7OyRz https://imgur.com/4mp24Oj https://imgur.com/hQLzhaU https://imgur.com/eJRdcho
