networking performance issue(s)
Recently, and I don't know if this is the fault of Windows or
of changes that Spectrum may have made, web surfing has slowed down. I can watch the process in the corner of the screen when I click a link and the steps that used to happen instantly take several seconds or stall completely partway through. My system has also grown cranky connecting to the net in the first place when the system boots. Sometimes I have to disable and re-enable WiFi several times to get past the "connected but no internet" problem. For fun(?), I tried disabling IPv6 in network properties for the WiFi adapter. This has gone a good way towards restoring performance. So, my questions a is IPV6 generally necessary and could disabling it have caused the performance improvement I'm seeing or is that just a coincidence? |

The enemy of wifi is other wifi applications running nearby. A strong signal will drown a weaker one, and you find out, that your connection becomes unreliable. If possible, use a cable or install a nearby repeater. |

My Velop router (3 units) produces a very strong signal so I don't believe that's the issue. No competing wifies in the house? digital TV, cameras, M$ trying to update computer(s) etc. ? |

I don't know about your digital TV but mine has its own router and shows up as another net work. What ever you may try to change the channel that your router uses, and see if that works. OR some routers have an automatic selection process, that picks the best channel for transmitting signal. On my router there is a Congestion detection function that checks determines the channel with the least congestion. One other thing has one of your other Internet devices changed, or has one been added. It is possible that one has changed and is sucking up all of your Internet channel -- 2018: The year we learn to play the great game of Euchre |

I have ATT uverse and periodically it bogs down and the router must be reset. When it needs to be reset one of the symptoms is their is no broadband connection -- 2018: The year we learn to play the great game of Euchre |

No competing wifies in the house? I don't know about Jason, but I have only one wifie in my house, and she's been my wifie for almost 60 years. |

So, my questions a is IPV6 generally necessary and could disabling it have caused the performance improvement I'm seeing or is that just a coincidence? Doesn't web surfing "performance", depend on DNS ? It could be the DNS lookup which is slow. DNS servers are usually arranged in pairs, and Windows used to have the dismal property of always checking the devices in the same order, even if one DNS address isn't actually working properly. Linux swacks them - a DNS which fails to respond, is put second in the list, the working DNS in the pair is first in the list. This keeps DNS performance high, even if one of the DNS devices is kaput. It could be DNS which is slow. it could be the making of a connection which is slow (a routing problem). You can run "tracert www.somedomain.com" to test the routing. The command stands for "Trace Route". You could override the ISP DNS setting (acquired via DHCP) and set it to 8.8.8.8 (google) or use the CluodFlare one that they set up. When DNS is busted in Linux, I slap in 8.8.8.8 to get things running again. (Without leaving it as a permanent setting.) Paul |

I've looked carefully at that potential issue and don't think it's the (whole) problem. I can watch the steps in the connection process when I click a link - it's in the lower-left corner of the Firefox window. Until recently, all the steps whizzed past. Now, there is a long-enough-to-be-noticeable delay between each step, which leads me to believe something's not right with the performance of "the stack". That's why I tried disabling IPV6. try this: http://netalyzr.icsi.berkeley.edu note that the web version requires java, however, there is an android native app. the results should help narrow things down. |

Have you tried switching off your modem/router for 20 minutes or so?

There's a neat, free utility, DnsJumper, that tests a slew of resolvers and picks the fastest two. The resolve times vary, naturally, but the fastest are always in the 10-25ms range and I'm still seeing that response time even with the mysterious slowdown. https://www.sordum.org/7952/dns-jumper-v2-1/ I've seen the same thing with Firefox at times. Of course, I usually have a half dozen windows open all the time, so that doesn't help. When it starts to be a problem I just shut down Firefox, then restart it. I know this doesn't address all your issues, but it is one thing to check. |
