Help I no longer have access after changing my router.

Hello, everything was working fine, but after replacing my router (Google Wi-Fi) with a new one (ZenWiFi BQ16 Pro), I can no longer add a network location in Windows 11 File Explorer. I spoke with ASUS, but they have no idea what the issue is, even after enabling SMB.

Thank for your help

Hello,

you can make a 3-Sek-Reset

Hello Becker2020, tank’s for your help, i do your suggestion but it’s doesn’t work

So what likely happened was that you had a fixed IP address on your NAS in one IP subnet (ie: 192.168.1.0 let’s say). Now your new router uses a different IP subnet (ie: 10.0.0.0 let’s say). So now you can’t communicate.

Before I even get to “fixes” let’s check a few other things:

  1. Can you see the NAS in QFinder Pro?
  2. Can you access the webpage of the NAS?
  3. Can you open a command prompt and ping the IP address of the NAS?

Check all these before doing anything else. If you can access the NAS via your web browser, then we have a Windows 11 issue and not a network issue.

Now if you can’t access the NAS (all of the answers above a “No”, then we have a network issue.

So here is what you can do (options):

  • If you know the IP subnet (that is IP address range) used by your old router, change the IP subnet on your new router to the same subnet. Then problems should be solved.

  • If you don’t know how to adjust the IP subnet in the new router or if you don’t know the old IP subnet then you need to make sure that DHCP is turned on in the router (likely). Then do a 3 second reset of the NAS as explained above. You will also likely want to reboot your PC as well just to make sure your PC is getting a new address from the router also.

So now if you do the reset, let’s not worry about adding the network location quite yet. Let’s now repeat the steps 1, 2 and 3 that I listed above and see where we are.

Let us know what happens, please.

What is your NAS model? Why would you have to enable SMB? (SMB should be active by default)

According to google:

The default IP address for the gateway (router) on a standard Google Wifi or Nest Wifi network is 192.168.86.1

The default IP address for the ZenWiFi BQ16 Pro is 192.168.1.1

Trying to add network drives in Windows 10 / 11 is hit and miss using the “Map Network Drives” button as devices often don’t show. You’re as well off typing the IP address into the Explorer address bar, then when you have a connection, pinning it to Quick Access temporarily.

First off you’ve got to get your network addresses sorted as @NA9D says.

Hello, thank you for your help. My NAS is a QNAP TS-459 Pro+ (4.2.6). I see my NAS in Qfind Pro, and I also see it in File Explorer under Network, but I’m unable to connect to the network drive when adding a network drive, even if I enter its IP address. I contacted Windows, and they told me to contact QNAP, that the problem is there.

tank’s to all

what error message do you get when accessing

\\NASIPORNAME

in your file explorer ?

Hello, thanks for your help. Asus is telling me to enable SMB, saying that’s the problem. i dont remember, i will comeback with the answer tonight

Thank’

SMB will be active on your NAS (main function), nothing for Asus to enable or disable

Hello, thanks for the help. My old IP is ..86.** and my new IP is ..50.*. I tried changing the router’s IP to ..86.1, but I can’t change the sub-IPs. For the three questions, the answer is yes to all three.

Thank’s to all

in NAS SMB is activate

No need to censor anything

a 3 second reset will set your NAS LAN to DHCP and it will automatically get an IP out of your new

192.168.50.x range

i do that, but i can’t add network location in file explorer

What do you mean you can’t change the sub IPs? It is fine to list your LAN IP address range as it’s not a publicly routable IP range anyhow. It would be much easier if you would at least give something like 192.168.86.0 and 192.168.50.0. I think that’s what you are saying.

I don’t know what you mean by sub-IP. You talking about the subnet mask? That should be 255.255.255.0. No need to change that.

When are you able to access the NAS from the web browser? After you updated the router IP or before?

Sorry if I’m not using the right terms: the old IP address was 192.168.86.1 (subnet mask 255.255.255.0) and the IP range was 192.168.86.2 to 192.168.86.244; the new one is 192.168.50.1 (subnet mask 255.255.255.0) and the IP range is 192.168.50.2 to 192.168.50.244.

thank’s

OK. Thank you.

Now, what is the new IP address of the NAS? And can you reach it via your web browser?

the old adress is 192.168.86.51, and the new is 192.168.50.168 a can reach it via web browser but not by file explorer

Check if your QuFirewall is active and disable it if so.

Allow/Deny List might also something to check

OK. So there is nothing wrong with your IP settings now.

I know there’s some funky stuff some times with Windows 11 and SMB. Make sure that your ASUS router is not blocking SMB traffic.

I’m not a Windows SMB expert and I’ll leave that trouble shooting to people here who know more than myself.

But you should be able to see the NAS in your network from Windows Explorer:

Expand the NAS and right click on whatever shared folder you want to map and select “Map Network Drive”
