Hi all,

I am aiming to use a TL-SG1016DE
to enlarge my home network as the VDSL router (O2 Homebox 6641, a re-branded Zyxel) has only 4 RJ45 ports.

I am asking you for help with solving a conflict between switch and router.
Once the switch is plugged into the router, all internet and network access crashes (also after switch factory re-set).

Router:

Internet access when directly plugging into the VDSL router works fine with router DHCP activated.
The router is set to use the 192.168. 1.x range, itself w/ 192.168.1.1.
Also no problem if I manually change it to use the 192.168. 0.x range.

Switch

I can directly access the router via 192.168.0.1 once the IP4 on my Win10 PC is manually set to some IP in the identical subnet 255.255.255.0.
If the static IP is changed, also no problems to access later directly.

Now the problem:

However, in order to accommodate the router DHCP, I logged on and activated DHCP.
After that, I can no longer access it directly (except for after a factory reset).

Now, If I plug the switch into the router, all traffic crashed, the router itself is also no longer reachable, neither is internet.

What am I doing wrong?
Can someone help?

Kind regards
andym

So you can reach your router under the IP 192.168.0.1 through the switch? Then everything is ok so far!


Now the problem:
However, in order to accommodate the router DHCP, I logged on and activated DHCP.

Why activate DHCP again on the router? It did work already if connecting directly to the router, right?

So just leave the IP of the router at 192.168.1.1, leave its DHCP settings (which depend from the base IP, BTW) and change the switch's IP to some free one from the same subnet, e.g. 192.168.1.2 or whatever is available in order to reach it without changing subnets. Make sure the switch does not use DHCP. Then connect the switch to the router and you should have DHCP if you connect to the router through your switch.
