Lizard system network scanner1/9/2024 Its worth looking at that wifi environment with a wifi scanner to see if any of your close neighbours have set up a 2.4 wifi network, on your operating wifi channel that is causing your pc to drop out. 2.4 Ghz wifi is tough to work in these days if you live in a typical neighbourhood. The other item to look at is the wifi environment. So, whatever the budget allows, I'd recommend going with a wifi adapter that allows 802.11ac, in order to maximize the data transfer rates. Essentially one data stream per antenna, although its possible to see multi-path streams with the right home environment. In both cases, the numbers of modem antenna would match up with the pc's number of antenna. The black Hitron modems have three 5Ghz antenna, where you could run a PCE-AC68. If you have a white CODA-4582 modem, it has four 5 Ghz antenna, which would allow you to run a PCE-AC88. The other approach is to install a pci card with an antenna set that can sit above the pc, possibly on a desk. Not very conducive to good wifi reception. One major problem with the dongle is that its buried behind the pc, which is usually metal case. There are a couple of ways to do this, one is to install a wifi dongle, and the other is to install a pci card. If you do decide to replace the card, I'd look for a wifi card that runs 5 Ghz so that you can shift that pc up into the 5 Ghz band. There is a good chance the current loaded driver is a generic Microsoft driver instead of the manufactures drivers. So, you might have to do some research on the network card manufacturers site to determine the last published driver and see what you have loaded. I wonder if thats the case with your network card? If the driver manages to update for some strange reason (it shouldn't), I have to roll back the driver or reload the current driver which I keep on hand. I have that problem with this particular pc and its video card. If the pc is several years old, as you indicated, there's probably a good chance that the driver is much newer than the card and that the current driver might be causing an issue. Best guess is that avast is preventing the ethernet and/or wifi drivers from operating correctly, or that avast is somehow preventing the ethernet controller and/or wifi card from before you replace the card, have a look at the drivers for the card. It should install and possibly give you options to select for connecting to the internet when the install is done.Ĭheck the avast forums for issues dealing with the application and internet connection if you continue to have problems. When that is done, reboot the laptop and reinstall avast. In that case, you should run the avastclear application to completely remove avast. However, if you find that isn't the case, that would indicate that the uninstall routine doesn't uninstall everything, and that there probably are settings left behind in a file or registry setting. In theory you should be able to simply reinstall Avast and connect to the internet as usual. If the laptop connected to the modem, both for ethernet and wifi, and you're able to cruise the web, then you don't have to use the ipconfig/release & ipconfig/renew commands. If you manage to get the laptop connected I would suggest running windows update to ensure all your computer is upto date. If you manage to get the laptop connected I would suggest running windows update to ensure all your computer is upto wrote: After that plug the laptop into the modem and open the Windows "Command Prompt" type: ***Edited you running any third party firewall or anti virus/malware protection? I suggest uninstalling it then trying again. Why all the other devices connect & this one won't? Maybe it's time to take it to the repair shop? If there was something wrong with the modem would the other devices connect to the internet? I don't understand it. When I run the troubleshooter I get the ethernet doesn't have a valid IP configuration. I have googled the problem & did all the things I should do to help connect but it doesn't connect. The Toshiba laptop connect so does the Moto g5. I get the icon with the exclamation point & it says connected no internet access. My HP laptop won't connect via wifi or ethernet.
