I recently changed my router to another model (ZTE H168N).

I got my wired internet connection working, and the results given by ipconfig seemed to be fine.

I checked my default gateway and it was 192.168.1.1.

Then I tried pinging it, and all requests timed out. This is especially weird since I do have an internet connection. I then tried the same thing on all of my other devices with the same results.

Also, I cannot access the router's configuration page.

What could possibly cause this issue?

Things that I have tried:

  • Disabling the windows firewall
  • Power-cycling the router including all devices
  • Double check the default-gateway's address

Edit: I have factory-reset the router as suggested. I did not work.

Here are screencaps of my current configuration: ipconfig /all arp-a

  • The firewall on the device could be blocking ICMP. – Zoredache Jul 20 '17 at 21:19
  • @Zoredache Do you mean the windows firewall? I've tried disabling it entirely with no results. – MattMatt Jul 20 '17 at 21:21
  • No. I mean the device. The `ZTE H168N` device. Every device attached to a network can have its own host-based firewall. A gateway type device almost certainly requires one, since it almost certainly provides NAT and stateful packet filter. It probably just has some stupid defaults that block ICMP. – Zoredache Jul 20 '17 at 21:29
  • @Zoredache This is one of the issues. I can't access the configuration page either, because if I type 192.168.1.1 as a url in my browser, it doesn't connect. – MattMatt Jul 20 '17 at 21:30
  • Have you tried resetting the devices to factory default configuration? – Zoredache Jul 20 '17 at 21:36

It's unusual but the router appears to be blocking incoming ping (ICMP) requests on the LAN interface.

This doesn't really hurt anything. But, it should be a configuration option in the router.

Unfortunately, the company doesn't even have a US support page and google returned useless information, so that's about where I stopped looking for a manual with instructions.

  • Even if the router did block ICMP, shouldn't the ping message say at least that it was blocked? Because right now it just says that it took too long. – MattMatt Jul 20 '17 at 21:32
  • No, typically if it is blocked you will see Request Timed Out. – Appleoddity Jul 20 '17 at 21:35
  • How can I configure the router if I can't access it's configuration page from any device? – MattMatt Jul 20 '17 at 21:39
  • You didn't say you couldn't access the configuration page, you said you couldn't ping it. Just because you can't ping it, doesn't imply you can't access the configuration page. Have you tried to enter `http://192.168.1.1` or `https://192.168.1.1` in to your browser? – Appleoddity Jul 20 '17 at 21:52

    Also, are you connected via wireless? Sometimes you can't access the router over wireless, it's a security feature. – Appleoddity Jul 20 '17 at 21:54
  • I have tested both on wireless and with cable. – MattMatt Jul 20 '17 at 21:54
  • Yes, I have tried both http and https variants – MattMatt Jul 20 '17 at 22:04
  • I don't know. Something isn't adding up here. Is this your router or one provided by a service provider? If you have tested via wired and wireless, then you must've been able to configure wireless at some point? If everything is good, I wouldn't worry about it. I'm not trying to be rude, but have you read the manual? http://enterprise.zte.com.cn/en/products/network_lnfrastructure/cpe/broadband/201312/t20131209_414437_6402.html It says you can ping it and access the web interface out of the box. If you can't then replace it. It's bad. – Appleoddity Jul 20 '17 at 22:10
  • It's a router from my ISP unfortunatly :( I think it's just my ISP scamming people tbh. – MattMatt Jul 20 '17 at 22:12
  • Then that makes more sense. This appeared to be an enterprise device. Simple fact is they don't want you to access it. It's probably managed. If you want to make a change to it contact your ISP. – Appleoddity Jul 20 '17 at 22:13
  • It's worth a shot to call your ISP and have them remotely change the settings to allow you to access the at least the web-based console. – Shankensteinium Jul 20 '17 at 22:25
  • @Shankensteinium Thank you! I will try that. – MattMatt Jul 20 '17 at 22:26
