Is it the fact that your internet connection is accessed by adapter

Hi, Is it correct to assume that, the internet connection will be established in the adapter settings , overriding any dns and ip settings in the router.
Is it better to configure thro ISP, rather than self configuration. Please say with reason.
Now some routers have no firewall settings, in the router. Windows firewall only blocks certain programs in computer access and not in router access.
How to configure windows firewall to work, but with not allowing any attacks from hackers.
How to know whether firewall is enabled in a router, if no such settings are visible.
If any further details are needed ,i will provide.

Gibson Research have a free port scanner.

If you click 'all service ports' it probes the 1st 1056 ports, and they will show as stealth if your firewall is working. If you repeat the test with the Windows firewall turned off and it still shows stealthed, then your router firewall is working.

Hi, Thank you for your answer to check the test in the absence of firewall. It shows that all the ports are stealthy with firewall enabled and disabled. There is no settings for firewall in the router dsl2730u, in my version.
but here is the concern. Avast scan says that it has vulnerability. Which result is correct. I will attach the main picture of scan results.
I addressed them regarding this dubious state, and the reply was , the avast scan scans from inside your computer, where as grc.com scans from outside. The logic seems to be incorrect as for as i am concerned.
They why avast shows this> is this a false positive? Or could i just ignore avast alerts.
It shows port 80 and 21 in the router scan. but not divulging any thing about those ports, These are http and ftp.

I don't know anything about Avast.

AFAIK, if your machine IP and DNS are set to auto, you get a local IP assigned by the router, and you use your ISP's DNS. I guess it's possible for the router data to get corrupted to force a different DNS. It's more likely some malware has changed your local settings - check in the panel.

If you set things up manually, you choose the DNS, and it over-rides the router. I use OpenDNS (208.67.222.222) and (208.67.220.220). You can also use Google (8.8.8.8) and (8.8.4.4). Make sure you know the gateway IP before you start changing things. See snip of my settings -



Whilst this may be a temp solution, if your router is compromised you might need further action.

Hi, i wish to point out that i have enabled use the following ips and also selected the google dns. What other things i do? I used the grc.com with both firewall on and off and it gives both stealthy status in both the results.
I had the default settings wan in router, which allowed ping in ipv4, which was shown as ping test failed in grc.com . But after i deleted that, grc.com denotes that all the ports are stealthy both in common ports test and services test.
What is your idea on
, the avast scan scans from inside your computer, where as grc.com scans from outside. The logic seems to be incorrect as for as i am concerned.
Please.
So from your suggestion, it is known that router firewall is already enabled but not shown in the router page.

What's the symptoms of your router hijack - are you being re-directed to fake sites etc ? F-Secure have a 'check for router hijack' page, but it is under maintenance ATM - you could retry in a day or 2.

The Feds have a page on DNS hijack where you type your IP in, although this was setup a few years ago when they were taking down some botnet servers, so some links are out of date + don't work.

Hi, I was once experienced with block of internet access for a few minutes.
The ipconfig shows 169.254.90.67,. which i know very well that does not belong to me.
i immediately changed the access points, by using the access points.
So, to be careful, i am asking for tips,.I also tried and found that fsecure is on maintenance.
By the by, avast hns, home network security scans, in its ARscan show many sites, like weebly.com, baidu.comtwitter.com, qq.com,webs.com.mail.ru, and so many ips, which pages i never visited. I saw that it in its log file.

169.254.90.67 is a link local address - not a hacker etc. AFAIK this IP range is assigned when DHCP isn't working.

Those pages never visited could relate to adverts. I won't mention the blocker software I use, because this forum relies on ads and frowns on adblocker discussions.

hi, Wasnot,
I must really thank you for valuable information of self creating of ips , in the absence of DHCP.
Does that mean, that while i power on the DHCP, was not getting the required ip address, so that it generated itself the said ip address. In other words, does that mean, that the ISP server is having problem .
Now, i understand from your link.
will it cease to exist once, the computer is able to get ip from my ISP,
These are all new to me and so much users.
When this ip was , acquired, the problem i noticed is no internet access.
I changed to the use the following ip address and after given the ip address manually, i could get the internet access. Why this behaviour , sir,
Moreover, something was being installed from s3amazonws.com, some version, i could not remember. Hence, i thought that my router had been hacked and replaced with new router.
In new router also, avast alerts, those things i mentioned in my post.
I value your suggestion, and would be more to receive advice on this.
What are those ips in avast scan i mentioned. i could not view any of the site, while this is going on. Are those sites are the programs in different pages/links of my browser access. are these normal behaviour.

I think you are getting the 2 types of IP mixed up.

When you connect to the internet your ISP gives you an external, public IP that the world sees, so to speak. This IP is usually dynamic in that it changes now and then. You can get an unchanging static IP, but this costs extra. If you go to any of the 'what is my IP' sites or type 'what is my IP' into Google it returns your external IP.

When you connect to your router, if it has DHCP switched on and your pc adapter is set to auto, the router assigns a local IP from a restricted range usually 192.168.x.x (there are others). These ranges cannot be used in www's. You need local IP's so the router can send data to the correct pc. You can see this IP by typing ipconfig in a cmd window (IPv4 address). The local IP is also dynamic, so if you plug several pc's into the router you may find you get a different local IP. I have several pc's, and set my local IP's manually, so I can identify each machine easily on my network.

The strange 169.254.90.67 you saw is a local IP assigned when either DHCP is not working, some setting is wrong or a device isn't working correctly.
