Question Home network - switch issues

[richbembo]

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 (UK).

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.

If this is a standard Layer-2 switch, then it should function regardless of the IP address of it's Administrative interface.

If the change to it's IP address isn't "sticking", then maybe the flash memory holding the config info is just old / corrupted. Maybe reset, then reflash, then reset, then re-config.

(I ran into a Netgear VPN router like that, like 10-12 years old. Config interface would only sometimes half-load, changes wouldn't stick, etc.)

Also, try a different web browser. Like Internet Explorer. Back then, many devices were specifically coded to work with IE ONLY, and wouldn't work right with Firefox or Chrome.

Another browser for sure. I've run into all sorts of issues, especially odd ones like what you're having from just not using the 'right' browser. Try everything you got and remember that portable versions are great for issues like this.

SLM2048

Am using the SLM 2048 as my core switch in a small environment,for distribution switch I have ESW520, SRW2048,catalyst 2960 and another SLM2048. Each of the distribution switches has a single link to the core. Prior to deployment I configured a management IP address on the distribution switches...

Factory reset the SLM2048 while attached to the network you want it on. Per that one search hit, it may pick up a DHCP address. See what devices show up in the router / DHCP server, look for the SLM2048 pulling a IP dynamically

I'll just also mention I had a set of Dell PowerConnect Smart L2 switches that would behave like this as well, and it was indeed a browser issue. Using classic Internet Explorer (not Chrome, Firefox, or Edge), would let me make the changes.

They're still useful switches, but I replaced them because I got tired of needing old IE to do anything on them, so they sit on a shelf. At least most modern switch web interfaces don't rely on Flash / Java anymore so a new switch should be less likely to bump into this issue again.
