I can no longer access the Default Gateway

A TP-Link modem used to give me access to what ipconfig in CMD says is its default gateway : 192.168.1.1 After years of use it would no longer accept credentials of admin/admin. Now it will no longer give access to 192.168.1.1 - it times out - and does that in 7 different browsers.
My ISP examined the issue and recommended a new modem. That new modem (D-Link) would not accept those credentials either; and also no longer allows access to 192.168.1.1 The ISP then recommended a second new modem - same model D-Link. It would not even let me reach 192.168.1.1
My internet is quite good most of the time, so that is not an issue. There are rare times when the internet is missing - and THEN I look around at what I can tweak to get it back, but I have no access to 192.168.1.1 The problem is the same on my laptop - connected through WiFi.
My ethernet-connected desktop is an upgrade of Win7 Ultimate 32bit to Win10 v1511; my laptop is a fresh install of Win10 v1607 - also 32bit

The 'Media state .. : Media disconnected' message is just telling you tht it is not now using the IPv6 connection . . nothing to be concerned about.

Lets test the IPv4

Hold the Windows key and press R, then type CMD to open a command prompt:

Type or Copy and Paste the following" and press enter


echo > 0 & PING 192.168.1.1 >> 0 & PING 216.58.199.174 >> 0 & PING google.com >> 0 & tracert google.com >> 0 & echo [/php] >> 0 & notepad 0


That can take a few minutes to complete, come back and past the result in a message here.

If you are on a machine with no network connection, use a floppy, USB disk, or a CD-RW disk to transfer a text file with the information to allow pasting it here.

Very strange . . The router is not returning a ping . . yet you are connected to the internet. Are you able to access the internet?

Usual suspects for ping fail:
- bad port on the router
- faulty Ethernet cable
- Ethernet adaptor on PC has failed
- Router has failed.

Have you tried a different cable? . . port?
 
#11 ·
Yes, internet access is mostly excellent. No, I have not tried a different ethernet cable. All 4 ethertnet ports are connected some or other device. I COULD try another port. But I don't think I will bother, because even the wifi connected laptop fails to access the default gateway, so it is not an ethernet issue. Moreover, the same with the other two brand new modems which connected by their new cables.

Being open to hacking the router may have been set to not respond to ping.
Older and even some newer routers have vulnerabilities that make them accessible from the outside.

I would hit the reset button on the router as you power it up to set it back to defaults. Then try your access again. Sometimes it takes a couple of resets for it to take.

There doesn't appear to be anything wrong with your pc since tracert showed the router and it uses icmp just like ping does. Appears the router has been configured to not respond to ping

'I would hit the reset button on the router as you power it up to set it back to defaults.' that was done several times during the sessions with the ISP consultants.
' Appears the router has been configured to not respond to ping' : ' Appears the router has been configured to NO LONGER respond to ping, because previously it did.

Hi, go to start search and type:- cmd right click on the returned cmd.exe and select "run as administrator" at the prompt copy paste:- (cmd's for you are highlighted in red)

netsh int ip reset (press enter)

Next, still at cmd prompt:-

netsh winsock reset (press enter)

Restart computer. Open a cmd prompt again as admin and at the prompt type:-

Ping 192.168.1.1 > 0 & notepad 0 (press enter)

If this fails still at command prompt copy paste:-

echo > 0 & route print >> 0 & route print 192* >> 0 & ipconfig/all >> 0 & echo >> 0 & notepad 0 (press enter)

Please post the notepad outcomes here, OR if the gateway ping now works let us know.

EDIT:- sorry, forgot, please try to access the router(192.168.1.1) using IE.

"Now that can be due to age/failed component/impending failure or its been changed from the outside." The two brand new modems can likewise not access Default Gateway. For over a year, when I turn on my Android tablet, it warns about the modem being insecure.

"You say you did the reset. I take it there was no change" It did not fix the problem.

"try to access the router(192.168.1.1) using IE." - Same result with 7 different browsers.
The connection still times out when attempting to access 192.168.1.1

SEBASTIAN42 just quoting and agreeing with the aforementioned conclusion really isn't helping you.

What antivirus are you using? what firewall software?

if you are proposing that three modem/router combo units all exhibit the same behavior [we can only go upon your unbiased observations] of no access then the conclusion has to be something with your pc.

you want to work on that?
 
#19 ·
Hi, well you have internet and the route table identify's 192.168.1.1. I asked you to use IE as it is more likely to not give security problems. GentleArrow is correct we would normally suggest a power cycle of router and computer and if this fails a reset, you say both have been tried, it would help to look at your AV and firewall, although it is not blocking access as you have internet, very odd, at this stage i suggest you open a cmd prompt (as admin) and type :-

netsh interface ip delete arpcache (press enter). Try now, let us know how you get on.

In regards to the AV have you at any time had another AV program (maybe a trial) of an AV installed? Same goes for firewall.

Can you access the router from another computer?
 
#21 ·
Here is an attempted repeat of the lost reply :

'netsh interface ip delete arpcache (press enter)' resulted in 'OK'
192.168.1.1 prompted : 'Problem loading page' 'The connection has timed out' 'The server at 192.168.1.1 is taking too long to respond.'

"Can you access the router from another computer? "
I had written that a laptop with Win10 v1607 can get WiFi to from the same modem/router

Would there be sense in trying any of these tests on one (or both) of the brand new modems ? involving a different PC - two different desktops have Win10 v1607, and Win8.1 or I can run Win7 Ultimate in THIS PC - all done with some, but manageable, effort.
 
#23 ·
I had typed the default gateway on the wifi connected laptop, and got the same failure - or does WiFi not count ?

I typed 192.168.1.1 into the browser's address bar on another ethernet connected PC - with Win10 v1607 - same failure to access the gateway

Using the new ones would be by substituting the new for the old - totally disconnecting the old and connecting the new modem instead.
 
#26 ·
I mounted the new modem and connected it to a PC different from this one; All went well.
Then I connected it to just THIS PC, and NO internet was available. I didn't bother typing the Default Gateway, because unless I have internet, the rest is immaterial.
So now this PC is again connected to the old modem - I have internet, but no access to Default Gateway.
 
#29 · (Edited)
On the other PC I could access the Default Gateway of the new modem, but not internet. Reconnecting to the old modem restored internet to that other PC.
When I wrote 'all went well' - I was referring to accessing the Default Gateway and getting the admin credentials accepted. It did not occur to me at the time to ALSO test for internet, as that had not been an issue. But when I did it was lacking.

Incidentally, the email I got referred me to I can no longer access the Default Gateway - Page 2 - Tech Support Forum but that 'page was unavailable'. I got back to this thread by starting from Tech Support Forum | Experts Online now for FREE Support!
