Ah, it’s starting to make sense, as I can’t be using 192.168.0.x. The router interface tells me I am using 217.155.223.50 . I’ll try the command with that address. ---

Again, you need to change that 217.155.223.50 address in your router settings. Plex is NOT going to work properly until you do. Also, you have left yourself wide open to attack from the net by using that address range. It is a WAN address, meaning it is completely open to the internet where anyone may discover it. Using a Private network address protects you from that type of attack, since no one can see your network from the internet. That is the purpose of Private IP Addresses. ---

Right, I get you, and your previous post. I will find out how to get a private IP address. ---

If you tell me exactly what make and model your router is, I will try to show you how to change things, as long as I can find the user manual for it. ---

Your router’s manual is a bit of a mess, it does not show the menus clearly. I believe you need to find the DHCP settings and then change the address range there. ![image](https://global.discourse-cdn.com/plex/original/4X/7/e/d/7ed6437c16715e8f88aabb54295725dbb2281355.jpeg) The settings shown above should be suitable for your LAN. ---

Thanks. I have asked my ISP for help also. Presumably this is why Plex seems to struggle to play titles (if at all); as you say Plex is not going to work properly as-is. ---

Look for _Distributing IPv4 Addresses_ or _IPv4 DHCP Server_ in your Fritz!box settings, hopefully you can track it down. If the Fritz!box settings have a search function, that may help you also. ---

use this page: [https://portforward.com/](https://portforward.com/) old as heck and very useful to figure out all the Basics. Even if it dont have your router the examples wills till help as there really isnt that much difference between them. Just keep in mind you are NOT port forward anything! So skip that.

That page wont help you, it is talking about using Fixed IPv4 addresses, which is not something you really want to do. You need to correct/configure the DHCP address range used by your router. ---

@bward149 #### SSH to a Synology NAS First fix the IP addressing. To use SSH, the NAS user must be a member of the administrators group. 1. Login to DSM 2. Synology Control Panel → User & Group 3. Edit the desired user 4. User Groups tab 5. Add to the administrators group and Save. Also, port 25 is a bad choice. It is reserved for SMTP (e-mail). If you were to run an email server on the NAS then there would be a conflict with SSH traffic. If you want to change the port number, pick an unassigned or unofficial port. See [List of TCP and UDP port numbers](https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers). #### Download & run DBRepair for Plex Media Server on a Synology NAS See this post: [How to switch library from imdb rating to rotten tomato critic and audience - #19 by FordGuy61](https://forums.plex.tv/t/how-to-switch-library-from-imdb-rating-to-rotten-tomato-critic-and-audience/933142/19) ---

> [@FordGuy61](#): > > [List of TCP and UDP port numbers](https://en.wikipedia.org/wiki/List_of_TCP_and_UDP_port_numbers) I have changed the port to 15 which seems safe. I tried to change the IP address to a fixed one but came unstuck when changing System Settings\>Wi-Fi\>Network\>Details\>TCP/IP to Private Wi-Fi Address\>fixed and changing the IP address field, but I couldn’t connect to the internet at all, so I put it back how it was. I will read up more about how to go about fixing my IP address to a steady one. ---

Re. fixed IP addresses, I heard from my ISP today, after I asked them how do I set a private IP address: “A private IP address is used only within your home network and is not accessible from the internet. These addresses allow your devices, such as laptops, phones, TVs, and printers, to communicate with the router and with each other securely. They are separate from your public IP address, which is what the internet sees. The FRITZ! Box 7530 AX already handles this automatically. It assigns a private IP address to every device that connects to your network, so there is no need to request or configure one manually. As soon as a device joins your Wi-Fi or is connected by cable, the router provides it with a private IP address from its internal network range.” He offered to help finding the IP of a specific device or configuring advanced settings. Is a private IP address done through the router, or through my computer? I read somewhere that it’s best to do it through the router, but that’s only an opinion, I suppose.. ---

@bward149 To change the IP address range on your Fritz!Box, log in to the user interface at `192.168.178.1` Navigate to **Home Network \> Network \> Network Settings** , click **Additional Settings** under “LAN Settings,” then click **IPv4 Settings**. From there, you can change the DHCP server’s IP address range to your desired values. I recommend using 192.168.178.20 - 192.168.178.200 if it is not already set to that. **Step-by-step guide:** 1. Open a web browser. (Firefox, Chrome or Edge, etc.) 2. **Enter `192.168.178.1`** into the address bar and press Enter to access the Fritz!Box user interface. 3. **Log in** with your Fritz!Box password. 4. Go to **Home Network** in the menu on the left. 5. Click on **Network**. 6. Go to the **Network Settings** tab. 7. In the “LAN Settings” section, click **Additional Settings** to see all the options. 8. Click on the **IPv4 Settings** button. 9. You can now change the IP address, subnet mask, and the range of IP addresses the DHCP server will assign.\* Click **Apply** to save your changes. You may be asked to confirm the procedure on the Fritz!Box itself. At step 9, if you are not sure what to change, then post a screenshot of the page and I will tell you what to change and how to change it. ---

Great, many thanks. I actually didn’t need to change any of the settings. as they were already as you specified (see screenshot). Plex seems to be behaving a fair bit more smoothly in the last few days. Hopefully it will stay that way. ![bward149](https://global.discourse-cdn.com/plex/original/4X/f/f/a/ffaf847b5af13efe9d0786e80097d0eebc002333.jpeg) [Previous page](https://forums.plex.tv/t/on-going-connection-issues/933762.md?page=1) [Next page](https://forums.plex.tv/t/on-going-connection-issues/933762.md?page=3)
