Home network - switch issue
SLM2048
00:23:eb:b0:c3:52 Hi there. Ten years ago I decided to wire my house with Cat 6. I also bought a Cisco (Linksys I think) SLM2048 switch. My ISP enters my house, and then is distributed by the SLM2048. The SLM2048 is now way past end-of-support but still works. Today I changed ISP from BT to Virgin Media. Problem: The VM modem/router is on IP address 192.168.0.10. The BT is on 192.168.1.253. My SLM2048 switch is on default 192.168.1.254. (To make this work I had to change the IP address of the BT modem/router to ...253 which in itself was traumatic.) Now, I need to change the IP address of the SLM2048 to 192.168.0.something so that it is on the same network as the VM router/modem. I cannot figure out how to do it. Every time I go into 192.168.1.254 (whilst going through the BT router) and change the IP address to 192.168.0.254 and the Default Gateway to 192.168.0.10, the SLM2048 admin page doesn't reload after I hit "Save" (obviously I guess). If I go to 192.168.1.254 I get a timeout. Can't ping it either. But then when I switch to the VM router so I am on the 192.168.0.xxx network, I cannot see the SLM2048 at 192.168.0.254 either. I end up having to factory reset the SLM2048, and reconnecting via the BT router and then I can see it again. Please help. |
Re: Home network - switch issue
Why did u have to change IP Address?
I always thought the whole point of these were plug and play and to auto assign an IP. |
Re: Home network - switch issue
I dont quite understand how you have your network set up.
What do you mean by going to the SLM2048 through the BT Router ? So atm, my only suggestion atm is make sure the Network Mask on all of them is set to 255.255.0.0, so you have just the one 192.168.x.x. network. |
Re: Home network - switch issue
Can you draw a simple, physical diagram of your network?
Also, is there any specific reason why are you using a managed/layer3 capable switch? |
Re: Home network - switch issue
Brief search shows that 192.168.1 is possibly used for the guest network.
If you set a PC to have a fixed IP on 192.168.1 can you then IP to the switch and change it to 192.168.0? |
Re: Home network - switch issue
If you know the MAC of the switch you can then make an ARP table entry via the CLI to give it a temporary IP in your home range so you can then access it.

Re: Home network - switch issue
If you have a machine with an ethernet port, give it a static IP address on 192.168.1.0/24 -
Say 192.68.1.2 with a netmask of 255.255.255.0 Patch it into the switch and open the admin GUI of the switch in your browser Go into Setup > Network Settings and set the IP Address mode to DHCP Just let the switch obtain it's IP config for the default/management VLAN from your SHUB/Modem and it will save farting about with DHCP reservations or static addressing. You will be able to look in the attached devices panel on your hub to check which address the switch has been allocated. |
Re: Home network - switch issue
I don't know the SHUB settings but on my router I configure DHCP range from .100 to .199 and use the lower numbers for network devices or clients I want to fix and .200.254 for things like printers, TiVos etc that I also want to fix but are more "publicly" available.
So I would still fix network devices like switches, routers, AP's to the low numbers. The range is big enough I can add new routers/AP's etc to replace older ones, get them working then retire the old. For some devices they still use DHCP but I fix the IP via MAC address. |

Better off just setting the default VLAN configuration to use DHCP and there's no need to worry about it when changing ISP again in the future. |

The .1 address is the router itself (default gateway), I'm only up to .12 on fixed devices. |
