And yes I did the upgrade to V3 firmware. It did not help.

Ok I made a new finding.

 

Until now I thought it was impossible to chain two managed switches but if I replace the “basement” switch by the unmanaged, I was able to chain two managed switches and at the end of the chain, I had a computer where I could access Internet.

 

this way  I thought I had identified a faulty switch, but if I keep only the 2 managed switches and move up in the chain (removing the unmanaged), then again I have no internet. 

 

so now I am puzzled. 

 

I guess the fault is in your network config. Maybe an IP used by another device, maybe something other mis-configuration. Change the IPs of the switches to unique ones outside the FritzBox 192.168.178.0/24 network, e.g. assign them 192.168.0.1 and 192.168.0.2.

 

And get the network set up step-by-step, device for device. There is no other way to find out what's the fault. Let aside the check for "it gets or does not get Internet" until you can be 100% sure that the switches can be found by their IPs (i.e. use ping, web UI access, basic connectivity checks).

Hi! 

 

At last, it works. The error was one of the long cable that was not working if put between 2 managed switches, but as soon as there was the unmanaged switch this was working. Somehow the managed switches don’t tolerate some cable issues very well.

 

hard stuff (hard to replace a 15m cable going through walls) but now all is ok.

Great it works now. Please mark the thread as solved by choosing "best solution". For example, in post #8 I suggested to check cabling. Thanks!

It does sound like a bad cable or something somewhere....since I used to have a chain of easy smart switches.

 

[ TL-SG105E v3 ] <=> [ TL-SG1016DE v2 ] <=> [ TL-SG108E v3 ] <=> [ TL-SG108E v2 ]

 

My router was connected to the TL-SG1016DE v2, but then I went to setting up vlans, and couldn't get vlan1 to move on the TL-SG1016DE v2, so its a doorstop now.... for the moment that spot has a DGS-1210-20 C1, but there's a 4200G-48 being prepped to replace it... since I need 21 ports...(and I can't use the TL-SG1016DE v2 to get more ports here.).  Eventually, it'll be more of spokes of TL-SG108E's off of the big switch....instead of the current chain... and do LAGG on the spokes...so that network backups won't impeded my Internet fix.

 

Hopefully, I can get my AppleTV connected before the 12th ;)
