        Hello again Lougers, today after a while I decided to post some questions

        For those that don’t remember I have been having weird issues with my network card and my modems this year

        Some may remember I promised you to test my network card in a different modem

        So I did it and I had different issues with both of them

        One of them (the one I had while I was away at home)  had an issue where  my wireless security stopped and it sent me NDIS errors. and Netwnb64 errors (that my network adapter wasnt working properly)  (I never lose internet connection here)

        the other one,  doesnt have that issue but it sometimes disconnect me from the internet or it has limited connectivity  even though the rest can connect.

        In both instances I can ping I must clarify

        naturally  each error that my netowork card is having with both modems  doesnt replicate in the other one   (in the one I have at hand right now, I am not having the network security issues and viceverse)

        My question here is:  If I am having differente issues in both modems and in both instances I can Ping,  Can I finally blame everything to my bad luck at having two bad networks?

        Just someone who don't want Windows to mess with its computer.

        We need a refresher of your setup to advise.

        Either link to your previous post or describe your 2 network setup.

        cheers, Paul

        lets see,  in both instances I am connected by Wireless,  both modems are 802.11n

        Problems with WLAN autoconfig and NDIS

        can an unstable connection make a wireless card act funny?

        I too was getting disconnected and things weren’t so great years ago and this fixed the dropped connections. This is a long shot as some drivers may not offer this setting, maybe your wireless radio driver has this setting (or some similar name) Antenna Diversity.

        What Antenna Diversity means is that the Wi-Fi radio can pick which antenna to use, yours may also never make the best choice.

        Open Device Manager as Administrator and find the wireless network adapter. There should be an Advanced tab with a list of esoteric settings. (Hopefully you can see something relating to the Antenna or Diversity in the list.) Options for Antenna Diversity may be simple like Auto (factory default), Aux, Main.

        The driver’s Automatic selection logic may be broken so you will have to try the other options, perhaps for your driver the new configuration is an instant result. (Depending on the wireless card Aux may select the external antenna port attached to the card; Some wireless cards have a short stubby antenna as part of the circuit, this maybe the one designated as Main.)

        The usual advisement applies be mindful and take notes, some of these settings are meant for debugging and changes may cause unknown effects.

        I would stick to the router that gives you a stable connection but has NDIS errors.
        Then you can see if the errors are worth bothering about.

        Sadly a few days ago, the NDIS issue started to appear in this modem too, therefore I think this is a problem with my network card

         

        What I notice is that the Wireless security  (in WLAN autoconfig) suddenly stops then starts again then stop and start again  in a bunch of seconds  then the disconnect issue or the NDIS issue appear.

        I also like to attach what Event viewer said

        as I said before, one of my Modems aren’t working properly it has DSL synchronization issues

        but if that was all the problem I wouldn’t worry

        the issue is that I disconnect when the internet signal is good.

        Those log entries are not errors, but they may indicate something else has a problem.

        Do you have any router that gives you a stable connection?
        Are you able to use an ethernet cable to the PC to eliminate wifi from the problem.

        cheers, Paul
