Is this slow WiFi your experiencing with Linux?
Did you install the firmware for your WiFi device?
If you want help with Kali your in the right place, otherwise you need the respective forums of the distro your using.
If you get a specific error, show it to us.
thank for reply @Eris2cats @Fred
that is error show me and even if download chrome only 112mb file may take 2hr 3hr to download and after a white it stopped downloading… i think its issue is in not kali version
i cannot upload image because i am new user
In Kali tweaks try changing the repo to use cloudflare CDN that may help with speeds of updates.
General speed issue, have you install the firmware for your device yet?
I have no idea what the device is, you’ve given very little info, if your not sure yourself, what is make and model of computer, as Eris has already said, show us some details!
‘that is error show me’
what error? what did it say? copy and paste the terminal text, your request and result, or post a screenshot, can’t help more when not enough information!

Error: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
I’m confused as to your set up now, earlier you say you were dual booting, which I took to mean running Kali direct on hardware from one partition, and Windows from another partition, and choosing which to boot up into.
later you say ‘Windows playing up’ which would only be relevant if you were using virtual machines, or WSL to install Kali as a guest inside Windows…
I have a similar problem. I tried fixing it by using git clone command but it is saying that the reprository is not present. You can try if u want may work in your case.
That problem of yours has nothing to do with their problem. Should have entered the missing key into any search engine.
i already set new key. kali linux blog explain they missing old key so that’s why that problem face but actually its different,it is wifi or network driver not compatible with machine internet card! may be thats why it slow speed. now i am using window 11 and here is super fast net but problem with only in linux os
thanks bro but i already try everything but still same thing internet slow working so now i am using window 11 and try to find best linux os for programming
You never did clarify if you are actually dual booting (running Kali direct on hardware) or using a VM (running Kali inside Windows as a guest OS)
You also never told us what the WiFi device was, its hard to help without all the information…
yes @Fred i was using dual boot with window 11 and kali linux but now i reset my laptop and installed window 11. if you help me i will try again dual booting.. i already keep 150gb unallocated space for linux.
yesterday i updated kali linux and it takes 4hrs to complete due to slow internet in only in linux… ok so then i reboot my laptop after update all but after reboot it throw exception on screen something went wrong message… during the login screen, i frustrated reset all and installed window 11(bill gates) does want to me install linux again in my machine hahahahahaha
That usually means you did the update wrong. Follow the documentation.
Also, whats wrong with kali in a virtual machine instead?
bro i was not using virtual kali but dual booting, install in different drive. when i start machine it asked me which you want to boot kali or window.
now i will try again to install no i am going to download new iso file and bootable pendrive let see what happened!
Hi…now i am posting this from kali linux… i do not know but its working now but internet issue may be check later but i installed now kali in my machine
