Windows 7: Is it the fact that your internet connection is accessed by adapter

Hi, As per your valuable advice, i went to the ISP and asked to configure the dlink modem, that i newly bought. The tech guy says that i should not configure the modem by cd wizard. He also says the av programs alarms are false and no one ever could access my computer except me. He reconfigured the same and i went to attend other things and after power resumed, i just connected this modem. I could not get internet access. I did not touch any settings.
The error was the dns server was not responding. The other time, the error shows, that windows cannot communicate with primary dns server. I know that there is no problem in their server.when i checked the connection status, every ip was ok, but dhcp disabled .
I will again visit to correct this modem configuration.
in the mean time, i have connected the old modem , teracom, which got me internet access. So, am writing this. What is the problem with the new configured modem?

The behaviour of the network is somewhat puzzling me.
i could get internet access in my old router, but on using the new router, configured by the ISP, the internet light is red.
Is there any command to fix this?
Because, if i go to the ISP, there the modem will work. will not?
moreover , my network has now become network 3. Please

If everything is set to auto in the IP panel, the DNS should come from the ISP. Have you tried the new router with manual settings for IP, Google DNS etc - the gateway (router) IP must be correct, and machine IP in same range. Also have you scanned for malware eg with your usual A/V and Malwarebytes.

Hi, I will try your suggestion. Yes, it was not set to auto detect. will try and report. But why this behavior of allowing one to have and another not to have.
I am learning network now. Normally nobody cares for router, if it works. But avast got these messages to probe further.
I am thankful to you for valuable tips.
Regarding APIPA address, why it needs to be assigned to itself if you have flawless adapter? There is one more thread on Apipa.
i only knew this from you. again thank you

Since you are learning about networks, you might find this desktop network meter handy -

Windows Desktop Gadgets - Network Meter Gadgets Version 9.6

it can show a lot of info - local + wan IP addresses, MBs up/down, firewall status etc. You can configure it to show as much data as you like. I have mine set like this -

Hi, I will definitely download this.
Sorry for late reply. My network was restored by ISP only now. I just viewed your reply.
Is there any simple way to know, that it is a general issue or individual issue in knowing the internet access.
I mean, if it is problem in ISP server or over head cable cut or in my computer.
I ask this question, as when i contacted the helpdesk, i was asked to trouble shoot and give them the error message. It gives, dns server is not responding. they asked me to change the dns server and access points . Probably the google dns and opn dns were told. I tried but could not get internet access.
Afterwards, i knew that it was not individual problem, but by overhead wire cut, which is common to the area. If i know this , i could have avoided his advice to know that it is general problem.
Lastly , was told by ISP, that each line is unique and no body could hack our computer. Is it true. He asked me to keep the wifi pw to myself, so that wifi could be protected. so, if the wifi pw is not known to others, your computer is safe. Is not it.?

All my stuff is hardwired using CAT, so I have wireless on my router turned off. If you use wireless, make sure you are using the latest encryption your hardware allows and a strong alphanumeric password. My router is rather old, and uses wpa2 - previous versions can be hacked by 'sniffing packets'. IIRC newer versions are available.

I guess the security risk with wifi is twofold.

1 - If someone knows/guesses/hacks your wifi password their laptop would effectively be on your home network and any shares on your pc might be visible. When setting up a home network, the problem is often actually getting the pc's to see each other, and it's tempting to use blank passwords and set the pc's to allow login with blank p/w to fix this (or even turn off firewalls). This not advised - all my boxes have passwords, but I have them set to startup with no login. I use remote desktop to access the pc's, and a p/w is needed (can be stored). If you don't use a home network, you could double check all shares or RDP access are off.

2 - My main worry about wifi hacking (and why mine is turned off) is that someone could 'piggyback' my connection to download illegal content - torrent movies, or even worse kiddy pr0n. It would be on my IP and it would be me who got prosecuted.

As for hacking from the internet, in theory firewalls only accept traffic that has been requested, and any other attempt at penetration is blocked. So if your router and pc firewalls are on, you should be OK (in theory).

Windows firewall only blocks incoming and allows outward traffic by default. This is because the average user would never get online if he had to set the firewall rules ! If you use a 3rd party firewall eg ZoneAlarm, all outward stuff is blocked by default, so when you 1st fire up Firefox, Chrome etc you get asked for permission to connect. This keeps happening until all your apps are setup. Some folk find this too much hassle.

There are free 3rd party apps that give windows firewall this 'block everything at first' function eg SphinxSoft -

Windows 10 Firewall Control: Sphinx Software

this functionality can sometimes 'save the day' if you get malware that wants to 'call home' to download more malware - or you might just not want some legit software keep trying to update

Thanks for the explanation.
I could not see your message, as suddenly there was a pop up alerting that windows defender finds, monitoring tool/actualspy has crept in and the security risk is high and prompted to delete it. I deleted it by selecting the button, but it keeps me alerting again, at frequent interval of 1 minute. I tried all sorts of things. My computer mouse arrow, hangs , i could not close any window. I shut down forcefully. Then i tried system restore, it hanged at the middle of it, just has to force close it. Then again, i tried and at last could get safe mode with command prompt, and then i tried chkdsk /f/r. It only saved me from total failure.

The thought of wifi pass word could be stolen from system by using some trojans are really pointer. Could you suggest how to do about it. one solution of AES encryption and grc.com alphanumeric password. But if it could also be stolen, then i think that there is noting left , but to altogether block wifi in the router.
If grc.com says that all is ok, but some av is showing vulnerability, which is to be believed. The risk of wifi , is there, but seldom ISPs are worry about their customers side. they think that the ip is assigned thro, a firewall data process, and hence very safe. I have asked about portforwarding of open ports to unused device ip on my system. If you know the answer, kindly let me know.
The monitoring tool,win32/actualspy was real in its devastation. It made my system very slow and everything is hanging in balance. I do not know, how it went off, from my system after, chkdsk /f/r
