AFAIK, the "public / home" type of network can be chosen in "Network and Sharing center" -> "customize".

In any case, I don't see a problem in connecting, but on the type of connection (its permissions), which are also dependant on other settings in "Network and Sharing center" (on the lower section of the respective window).

Avast doesn't change connection settings (permissions), but the active firewall (which also changes with installation / uninstallation of AIS) and System Restore could.

In addition, Windows Seven Starter has its own restrictions.

Thanks ady4um,

It wont let me change the public/private network selection after uninstall of AIS (it doesn't recognise it properly as a network- customize does not appear)

After system restore to before the uninstall of AIS, public/private network can be selected as described.  Networks are recognised and working.

So my active firewall is Windows Firewall.  The settings for this seem to me to be exactly the same before and after the uninstall of AIS..... with one difference- the network is correctly shown as a Private network and named when AIS is installed.  

After uninstalling AIS the windows Firewall settings recognises my connections now as a 'Public Network' and says 'connected', although the details then shown are as if not connected, and by 'private network' it now says 'not connected'.  I doubt this matters, except to show that it's no longer recognising my network for what it is and isn't properly connected.

I have restored all the default settings for the windows firewall.

I have also tried turning the firewall off altogether.  

Does this eliminate the firewall as a cause?

Is it significant that when I try to set up a new connection that Windows tells me it 'did not detect any networking hardware', even if ethernet cable is plugged in?  This isn't the firewall causing this, or is it?

Many thanks

Where can I access these connection permissions in the 'network and sharing centre'?

Bear in mind it isn't recognising any connection to investigate the properties of.

On the left list I have

Manage wireless networks (this seems the same as normal)
Change adaptor settings (this is blank)
Advanced Sharing Settings (nothing relevant. again it show's I have a public network profile- but as it doesn't fully recognise the network I can find no way to change this.)

On the Main Page I have 'change network settings';
-Set up a new conn. or network (>conn. internet > Windows did not detect any networking hardware)
-Connect to a network (shows right hand conn. signal strength notification)
-Choose Homegroup and Sharing Options (Must be on a network first!)
-Troubleshoot Problems (has no solutions)


None of these allow me to specify or change permissions?

First, although it may seem evident, have you rebooted after uninstalling AIS and before testing the network settings?

I would suggest running the removal utility of avast for each and every version you ever had installed (not just the last one). For each run of the removal utility, reboot in between (into Windows Safe Mode)

After the removal utility, you said you don't have (new) network connections really working. Do you have / know the correct settings? If you don't then before uninstalling AIs take note of the supposed correct settings and only then start with the procedure.

Now that you have taken note of the correct settings of your network connections (the ones that should work), and that you already cleaned up all remnants of avast, simply go and manually create new network connections. If you have some "previous" network connections that are supposed to be working, but they don't, then after creating the new ones, go and delete the old ones.

My guess is that something in the System Restore points is somehow corrupted, so your network connection settings are being changed. I am not a developer of avast, but my guess is that AIS (uninstallation) is not changing the network connection settings. Maybe the default settings are activated when you remove Avast Firewall, and the defaults are not good for your situation.

Whatever the case, just use the correct values to create a new connection. That is, if Windows Seven Starter lets you use those specific settings.

Thankyou bob3160 and ady4um.

I have rebooted after each stage of the uninstallation.

I am now trying to record my current network connection settings after a system restore to before the AIS uninstall.  The network is operating fine and connected to the internet (albeit unprotected).  

However, the network does not show anywhere. My network connections page is totally blank.  No local area connection icon, no wireless connection icon.  Here is where I expected to be able to find my network connection settings.

So I have opened the cpm and copied the 'ipconfig/all' details into a document.  I think I need to know if these are likely to be the correct settings, or if in fact these too are damaged thus resulting in my network connections page remaining/appearing totally blank even after system restore.

Should I continue with the AIS uninstall and attempt to manually create a network connection with these settings, or try some further investigations of the network before uninistalling, whilst the network is at least accessible and partially visible to ensure I have correct settings?  Any advice?

@edders,

You post is a bit confusing.

This:

The network is operating fine and connected

seems not so congruent with:
Quote
My network connections page is totally blank

You previously said that before uninstalling AIS, the Network connection being used was visible, but not after uninstalling AIS. Now you are saying something different.

Try to follow the instructions to "record" (take note) of the relevant network connection (settings) when they are visible, and create a new one (with a different name). After uninstalling AIS, use the new connection just created.

Indeed ady4um, I apologise- I'm not so good with the terminology having had no training and piecemeal self education, so please bear with me.  I will try my best ;)

By my network functioning normally I meant that I could access the internet (it's all I use netbook and home netwok for) , and the connection showed properly in the notification window (from the system tray? Bottom right)- it is here that I meant it looks normal, rather than the actual network connections page.  I don't believe my network connections page has been functioning normally since the first uninstallation of AIS- I think it has been totally blank.

Thanks bob3160 for the link.  Unfortunately that was for XP, whilst I'm on Windows 7 Starter.  It did lead me to this page however http://social.technet.microsoft.com/Forums/en-US/itprovistanetworking/thread/19daf9d3-48ef-40c4-82ba-3e8931189486/  

Even though this was for Vista, I have gone through every process detailed on that page with the exception of using the clean boot method.  This is what I think I must try next, as it's the only option I have left to go with.

I'm not sure how to progress immediately next though- I've system restored to before the uninstallation of AIS so the network connection is open, though it's not a 'clean' restore it seems, and AIS doesn't work correctly.  Should I uninstall AIS before I do this clean boot method to try to recover my network connection icons?

If I do, and my connection settings are reset by the firewall change, any subsequent recovery of my network connection icons might not lead me to the correct settings.

On the other hand, I might go through this clean boot process and somehow recover my icons, only to have it all thrown into disarray again by the uninstall of AIS.  (but i guess at least I should have some settings then, and can try to address the lack of icons again if the issue remains)

Clearly I don't have much of a clue as to how all these bits integrate.  Should I uninstall the dodgy AIS (and thereby close my network connections) before I progress any further with this clean boot method?  

Any advice on anything would be welcomed.  I am a little out of my depth, but live in a very rural location and professional help isn't an option for at least another week.

If all else fails I've noticed the reset to factory settings button  :o  Could be a drastic but pragmatic solution? Does this reset to before the OS was installed? I have no way to reinstall windows

Many thanks

It will reset your computer to the way it was when you first brought it home.
You would loose any personal settings and any programs that were installed.
You would also need to do all the updates that happened since you brought your system home.

First, beware! The "factory defaults reset" will probably wipe any personal documents or data. So before such a drastic action, you should have a backup.

I don't think you need to go that far though. If you have the Network Connection working (not the tray icon, but the actual Network Connection which can be configurable with all sort of settings) then write down the settings of that currently working settings.

With those settings, manually create a new connection (Network and Sharing Center -> "set up a connection or network"). Then uninstall AIS and reboot. I repeat one more time that the uninstallation of AIS should NOT touch your network connections, specially this one that you manually are about to create.

I'm sorry to say that there is not so much that we can say here in the forum. We can guide you, but there is a certain limit as how much we can go by just posting in a forum.

If the manual creation of a new network connection with the correct settings won't help (or is not possible), you should try to find the correct settings from you Internet Service Provider (ISP), just as the first time you set it up in this particular system.

Maybe someone else has some additional suggestions or some additional method so to find out why this is happening to you.

Thanks for your help ady4um.  So this is my problem- the lack of a proper configurable connection. 

I'm assuming that the ipconfig/all info doesn't contain the settings I need?

I am trying the earliest system restore point I have to see if the connections work, and then will try this clean boot method.

I will worry about uninstalling AIS and installing virus protection last of all.

What I can't understand is how is it possible that you are connecting to the Internet (before uninstalling AIS) but there is no network connection. You may not see it, but it should be, somewhere. Either there is "some" type of connection, or you are wrong about having been able to connect to the Internet in such situation.

The ipconfig is not enough. You need the settings from your ISP to set a correct Network Connection.

All this is valid, assuming your Network drivers (wired and/or not) are working correctly.

Well it's certainly connected- checked on the bbc news (I don't have active anti virus, so I've only checked here), but I certainly can't find that connection.

And if I try to set up a new connection like this it still says 'windows did not detect any networking hardware'

I have noticed that my device manager page/folder is also totally blank/empty. (my computer> properties> device manager).  This seems strange to me.  Is it so?

What do you mean "can't find"? Can you attach please a screenshot of the "Network Connections" Window (where the connections should be displayed)?

If you don't have network hardware (drivers), then you can't connect. Sounds logic, doesn't it? So if you are able to connect, you should have some kind of network hardware, either wired or not.

Yes, it is strange. Unless you are using some "guest" Windows user account, but even in such situation, device manager wouldn't open at all.
