Internet access problem since I upgraded firmware

Hi Mihir,

Can't give advice on Mac mini problem but your network issue sounds like a problem with your router handling the switching duties as well as Internet/DHCP. General recommendation would be to connect your router to a dedicated switch (say a Netgear GS105 or GS108) and run your ethernet connections to your NDX and other devices from this switch.

I agree, all the symptoms indicate the Deutsche Telekom router can't handle the data packet flow.

Very few ISP routers are suitable for audio streaming, especially high res.

A simple solution is to add a switch as sjbabbey advises

Thanks a lot. I will try to get one and put it in place this evening.Whats curious is that it used to be fine and since the firmware upgrade something changed. Either way, thanks to both. I will try a switch asap.

I think you only need a switch in a complex network. How many devices do you have?

Have you done a complete network restart? Power down everything from the Modem/Router downwards and then power back up after a minute or so in order leaving a minute or so between each.

A switch won't do any harm other than burning some electricity but, as you say, if it was ok before the firmware upgrade then it should be ok after.

Are you using fixed IP addresses? If so, it may have changed when the update reset the streamer to factory settings. That's what happened to my SuperUniti. 

Good point HH & must be why Mihir links it to the f/w update 

We've discussed this before, but I don't have fixed IP on the individual devices & leave all these as DHCP.  In the router I set each device to fixed (static).  This "reserves" a specific IP address to each devices MAC address.

Nothing gets changed with updates upgrades or restarts - the only way it will get changed is if you revert the router to factory default.

Hi. This forum is just great. Thank you.

i have learned a bit about switches. if I got it right the switch would mean that the Mac mini and the ndx could do their business together more directly? As an Internet connection (ignoring i radio ) is not needed. This would relieve the router of a heavy task?

A full sequential power down, router reset and then one by one start up would allow the router to re build the network and illuminate any crossed references In allocating IP addresses (they are not fixed, beyond my competence)?

My network is compromised. The router is 50 meters away from the apartment so the routers wifi will not reach it but the aprtment is generously equipped with ethernet ports everywhere.

The router feeds four wired Ethernet ports and does all the dhcp work - ndx, local german iptv, a Mac mini which is the music hub - and an airport express which serves all other things such as lap tops, phones, iPads and Apple TV As a wifi device only. 

Will try try and get a switch and follow above process To reset the network. 

Should yhe the switch come between all connections to the router or selectively? For example, leaving only the music streaming chain on the switch and the rest directly to router?

The switch should connected to all the locations & only one ethernet from the router.

Have all the devises on the switch live before powering the switch,  that way it "learns" all the connected MAC addresses quickly
