Forum Index : Microcontroller and PC projects : Windows 11 - very slow internet browsing problem....

Anyone seen or heard of slow internet access on W11? I visited a guy the other day complaining that all websites were really slow since his laptop automatically upgraded itself to W11. Unfortunately, that was about a month ago, so we are well outside of the ten-day period that W11 gives you to roll-back to W10, so he's stuck with W11 now unless he does a full clean install back to W10, which he is unwilling to do - at this point. Anyway, what happens is that for ANY website you try to visit, on any of FOUR different browsers I have tried on that machine(Edge, Chrome, Firefox and Opera), the result is always the same - it refuses to connect to the site moaning that it cannot resolve the IP address. If you leave it alone, it DOES seem to work it out for itself, and then the pages load, but it is causing HUGE delays and frustrating the guy to no end, and I can respect that, cos if it were my laptop, I'd be wiping it and downgrading back to W10 or perhaps just move it directly to Linux Mint. Anyway, that is not an option for this guy, so we need a W11 solution. He is adamant that this was NOT an issue when the machine was running W10 - websites just opened instantly. He has a Gb fiber connection, so internet speed is not the issue, it is a W11 issue. That is also backed up by the fact that both a portable W10 laptop I have and his phone and my phone can connect to his WiFi, and the internet is super quick to load any page on those devices using the same WiFi connection. This appears to be specific to W11. Anyone else here seen this issue with W11 installs? It appears to be W11 at the root cause, cos it does not matter what browser you use, you get the same delays and messages, and all are the same - wait a while, and the page then DOES load, but as mentioned, this is introducing lots of delays and making the man angry, and I don't blame him after playing with the machine for half an hour trying to get websites to load, I was getting annoyed at his laptop myself!  ALL FOUR browsers are fully up to date. That was one of things I checked immediately in case he had an older version of any browser, that might not support W11, but they are all up to date, and Chrome and Opera were clean installs just to see if they worked any better, but they didn't. W11 on his laptop opens other non-internet apps immediately, and the speed of W11 on his laptop is not lagging when opening anything else, just the internet is really slow and unreliable. For every site you try to go into, ANY browser sits there with the busy icon for about ten seconds or so, then it spits back that it(the browser) was unable to resolve the IP address for the site, and we're talking some of the most popular URL's out there like facebook, youtube, twitter etc - they ALL fail with the same message and complaint. A quick duckduckgo search shows that this would seem to be an issue for others using W11, but there does not seem to be a common solution to it, and many pages simply talk about resetting your modem and rebooting your PC, which is NOT the cause of any of this, or other devices connected to the same WiFi would have the same symptoms, but they all work fine. Do any of the members here have any suggestions other then "Throw it out the window" or "Install Linux"? Smoke makes things work. When the smoke gets out, it stops! |

Hi Grogs, This may be caused by W11 trying to use IPV6 for DNS resolution. Some ISPs do not yet use IPV6. This shows how to find the correct place to change the settings for each adapter. link Just untick the IPV6 box. (I presume this part is the same as W10) Anyway it will be a problem with DNS resolution |

Excellent, thanks chums - I will try those out.  Smoke makes things work. When the smoke gets out, it stops! |

How does he connect to the Net? WiFi or Ethernet. Bad drivers for either can cause grief, especially WiFi. My Linux laptop WiFi is virtually unusable but Ethernet fine. Other tests: try downloading a large file to see if a single file can run at a reasonable speed. Slow DNS will not affect a large file (much) Check with Task Manager to see if the antivirus is hammering the system. Try changing the DNS to google etc. Jim Edited 2022-02-17 14:40 by TassyJim VK7JH MMedit |

Howdy everyone. Disabled IPv6 as suggested by morgs67, and everything is back to normal, sites load fast and the problem has been fixed as far as I am concerned. Thanks everyone, but morgs67 wins as that suggestion seems to have fixed the problem completely. Smoke makes things work. When the smoke gets out, it stops! |

It's stuff like this, that makes me wonder why Microsoft would enable IPv6 by default, if I may paraphrase you for a moment. Yes, it is the up and coming new IP system, but most of the planet are still using IPv4 protocol, so having W11 try to talk to sites(well, more so resolve the IP address for a site) using IPv6 as the FIRST attempt - when most sites still use IPv4 and not IPv6 - seems like an odd decision to make. To me, anyway. One would think it should be the other way around: First attempt should ALWAYS be IPv4, and if no talkie, then try IPv6 and see if we have talkie. But that's just me.....

I'm not sure if Microsoft are completely wrong in this. IPv6 has been on the cards for a long time now so looking for it first might seem to be a good idea. It could be that the implementation is poor, that a failed attempt isn't registered quickly enough. That might be a result of ISPs not being ready to handle IPv6 - and they've had plenty of time to be ready now. I'm wondering if the more users search for IPv6 addresses the faster the DNS caches will build up and the faster the system should run. Disabling IPv6 in Win 11 might actually be counterproductive. It seems strange coming to the defence of Microsoft. lol Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

It could be simply that your ISP hasn't enabled IPV6 yet to their DNS servers It's easy to change it yourself, it's almost the same steps as you did to disable IPV6. Use one of the many public DNS servers, this is step by step instructions incuding a list of free public DNS servers like this  |

@ both Mixtel90 and lew247: You both have a point. Actually, it may possibly be more of a New Zealand ISP issue in that THEY have not moved away from IPv4 yet, whereas perhaps places like America, Australia, England perhaps they have already moved to more IPv6 then IPv4, in which case and countries, there would be no issue there. Food for thought. Perhaps I was being a little hard on Microsoft there. Smoke makes things work. When the smoke gets out, it stops! |

it there any real need, from the domestic customer perspective, to have anything to do with IPV6? as it stands, the ISPs (as i understand it) transparently provide network address translation (NAT), so that the customer equipment need not know anything beyond IPV4. btw: my niece recently changed over to TrustPower for electricity, gas, and fibre internet. they gave her a new 65" TV, along with an Amazon Eero 'wireless router thing'. she found that Disney+ (streaming video) didn't work without frequent pauses, until we disabled IPV6. cheers, rob :-) |

Yes, I would have thought so too. However, it would seem - perhaps just a NZ ISP thing - that IPv6 has maybe not been taken up yet in any major way with our ISP's in NZ. Interesting that you had a similar kind of internet interruption issue until you disabled IPv6 too, so.....  Smoke makes things work. When the smoke gets out, it stops! |

When IPv6 was being designed there was no NAT. It didn't exist. That's one of the reasons that take up of IPv6 has been so slow. That and the release of huge blocks of IPv4 addresses that were being held back or allocated to users who no longer need them. There isn't currently a great shortage of IPv4 addresses. IPv4 is more secure for domestic users behind NAT anyway. In a fully IPv6 world every single device has its own address, including light bulbs, washing machines, toasters... Can you imagine the effects of DOS attacks on random IPv6 addresses? Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
