Question Router to Switch to Switch to NAS

[Colin_52]

Hi guys

hoping someone can help me? I'll try and keep this short and to the point.
I have multiple Nvidia shields that run kodi through cat6 ethernet, purely to watch my movies on from a local NAS. Everything was working fine until i decided to change the location of my NAS.
Originally my set up was this: 8 port POE Switch (TP-link LS108)
1. 5 port POE switch (TP-link LS105GP) (Summerhouse)
2. Nvidia Shield
3. Nvidia Shield
4. Nvidia Shield
5. Nvidia Shield
6. IP camera
7. NAS
8. Router (TP link Archer AX72)

Switch from no:7 (TP-link LS105GP) (summerhouse at the end of the garden)
1. Feed in from 8 port switch
2. Nvidia Shield
3. IP camera
4. Empty
5. WIFI extender (TP link)

All Nvidia Shields + laptop and phones could find the NAS drive, everything worked perfectly. The NAS was located in the room next to my bedroom and makes a bit of noise at night. So i decided to move the NAS to the Summerhouse. I read that you could daisy chain network switches.
Now my set up is
8 port POE Switch (TP-link LS108)
1. 5 port POE switch (TP-link LS105GP) (Summerhouse)
2. Nvidia Shield
3. Nvidia Shield
4. Nvidia Shield
5. Nvidia Shield
6. IP camera
7. Empty
8. Router (TP link Archer AX72)

Switch from no:7 (TP-link LS105GP) (summerhouse at the end of the garden)
1. Feed in from 8 port switch
2. Nvidia Shield
3. IP camera
4. NAS
5. WIFI extender (TP link)
I can't locate the NAS on any of the Shields running KODI or my laptop. I'm ok with following step by step instructions but i don't know too much regarding networking.
Sorry for the long post, but it was the best way i could explain it.

If you have any way of reaching the NAS admin interface, then you should be able to get its IP address (or the fact that IP address is failing). From each switch you can run a

traceroute

to that IP address to see the route it takes (in Windows it is

tracert

). Any device that can reach the NAS admin screen will allow you to ask the NAS itself about how it is connected.

So I assume you just didn't put it in your list. You have port 7 of the main switch that you say goes to the remote switch. You did not list a port that this cable plugs into on the 5 port switch.

Does the NAS function if your remove the remote switch and plug the cable in the remote room directly into NAS. It should all you are basically doing is switch which port on the main switch it is plugged into.

When it is running with the NAS plugged into the remote switch can you ping the IP of the nas from a pc in the main house. What happens if you plug a pc into the extra port on the remote switch can you then ping the NAS.

The switches should be completely invisible to the network. Their really is not much difference between plugging the NAS directly into the cable in the remote location or putting your 5 port switch between. Of course all the device in the remote location share the 1gbit bandwidth back to the main switch so if you had servers instead of the nvidia shields on the main switch talking to the nas there might be a performacne difference.

It sounds like 1 of 2 things happened.
1. Your NAS didn't have a static IP, so when you moved it, it came back up with a different IP, and everything got confused.
OR
2. Your NAS has multiple network ports, and maybe you plugged into a different one than before, which resulted in a different IP (see #1)

Check on that. I always hard code my NAS IP(s) to one that is outside the DHCP range my router/dhcp server is handing out.

Other than that, I don't have any other ideas, other than reboot everything

Thanks for the reply's guys, any info is always welcomed. I'm currently renovating my house, hence the moving the NAS around and my delays in responding.

I have edited the OP to include the feed in from Switch to switch.

I can plug the NAS backing to the 1st switch and log into the interface. Then i could check if it has a static IP..

I ran a CAT6 cable up the garden into a RJ45 face plate, then CAT6 to switch, doesnt make much difference but thought i would share.
My laptop s a Surface pro, only works on wifi.

What i will try next. plug the NAS directly into RJ45 face plate, see if any of the Nvidia Shields or laptop pick it up. Then get the ip details

I've logged into the NAS (QNAP TS-43X) through the 8 port switch and located the Network and virtual switch tab. My Nvidia shields and laptop all picked it up without any issues or changing paths.

IPV4 = Obtain IP address settings automatically via DHCP
DNS = Obtain IP address settings automatically via DHCP

The IP address stated in Network Interface is different to the "current WAN IP" in the overview.

I'm happy to post the ip information as long as i'm not leaving myself exposed lol, I'm not really sure what i'm looking for or at lol

Not sure what you are referring to. Does the "NAS?" has some kind of WAN ip. I would not think it does but there are models of NAS that can do vpn.

The only IP that is even slightly sensitive is the WAN ip on your main router. Pretty much the only real risk is denial of service attacks. Children that play shooter games tend to take losing badly and have been know to attempt to take someone internet connection down as revenge. The hackers check every IP all the time so it doesn't really matter if you post it on some forum or not you will be scanned likely multiple times a day.

Although there are many other ones the most common private IP you see used in home networks is 192.168.x.x. This whole range of IP is private which means it is not actually on the internet and many people use the same IP in their house so it means pretty much nothing.

DHCP should be fine but most people like to use a static IP for their NAS devices. If you do not use static IP then you are dependent on microsofts discovery abilites to find the NAS. Much more stable to just put in the IP address that never changes.

This though should not really make any different. The only thing I can think of is you have a second router someplace and it is responding to DHCP requests and giving out conflicting IP. Switches again have no concept of IP address so it really should not matter how you connect thing to switches.
