Maxing Out Download Speed But Very High Ping

gravypanda108 · Sep 9, 2018

I didn't have any issues until today. My download speed has a max of 20Mb/s (Best I can get here) and I normally can get a ping of well under 100 ms. Whenever I run a speed test or look in server browsers, the ping is around 700 - 6500 ms, which is pretty ridiculous. I made sure no one else was downloading/streaming content. I've tried rebooting the router (Linksys W52 something, lost the model sticker and box), restarting my PC, reinstalling drivers, etc. None of which ended up working. I'm using an Intel 1217-V Ethernet Adapter on Windows 10.

I would try going to control panel network and sharing center and where your wired connection is click on it and click properties. The next popup will give you the ethernet connection. Click the configure button click either the advance tab or the blanks tab, (depending on what your software give you). Go to speed and duplex dropdown box and other than auto negotiation try the 100 Mbps at full duplex and check your speed with speedtest.net. if that don't give you full speed try the 100Mbps half duplex and speed test again to see which one works better.

this is called bufferbloat. it's normal to happen, anytime in networking when packets can't move to the next point they sit in a buffer. the buffer has a size and all packets drop over the size. dropped packets is what signals TCP to slow down. changing buffer size can help. it shouldn't really be going over 1000ms. recent studies have shown that buffer sizing should be a lot smaller than what was previously thought optimal.

to keep it low QoS with AQM has been made. fq_codel being the latest. standard networking uses FIFO, this uses round robin. packets with large flows buffer/drop with a higher weight than a small flow. gaming will not buffer if your connection quality is good @ 75-95%. this is the only requirement for qos. you have to throttle your connection slightly so packets only buffer on your router running the qos, otherwise the rules of where it's buffering would be used.

edge router x, ddwrt, openwrt, ipfire all have it. if you're having issues during games this is the best solution. DSL reports has a bufferbloat check. it's mainly used to test your AQM.

I put QoS on for my PC and set it to the highest setting. Everything seems to work now, and I made sure I'm not sucking bandwidth from other PCs. Thanks for the suggestion!
