[Cerowrt-devel] 3.10.32-4 issues

[Cerowrt-devel] 3.10.32-4 issues

[Sebastian Moeller]

Hi All,

I just upgraded to 3.10.32-4 and locally all looks quite well. Both my macbook and my nexus 4 get stable connections to cerowrt over the 5GHz radio (HT40+ channel 44 country code: DE), also the machine on se00 gets a decent address. That is all machines get decent IP4 addresses, only cerowrt gets a working ipv6 address.
	Unfortunatelly the only machine that can reach the internet is the cerowrt itself, none of the connected machines can reach the internet (they can reach each other just fine)
	Here is a bit information from the linux host on se00:

To me this looks reasonable and I am unsure why the machine does not reach the internet. Interestingly on the first login to cerowrt routing seemed to have worked, but once I applied the set of changes I typically apply to customize cerowrt for my home network routing somehow went bust.

I just noticed that the lan and guest zones were empty, so I ant an reassigned them, but still the connected computers can not reach the internet. If there is anything I can do to debug this, please let me know, otherwise I will ref lash the router back to 3.10.28-16 tomorrow…

those zones appear empty in the gui because we use the + syntax to join them,
which the gui cannot interperet.

there are a multitude of issues with 3.10.32-X at the moment. I am at
a conference. Felix is on vacation. Don't try it. I keep hoping to
spend an hour with the openwrt devs here to see everything that is
going wrong now that hncp was nearly unanimously
approved by the homenet working group as the way forward (yea!)

The last patches for dnsmasq landed last week and simon tells me he
plans a stable release soon.

Hi Dave, hi List,

	Ah, I had not noticed that these were always empty, sorry.

	Too late ;) but since I could not get to work I reverted to 3.10.28-14 which worked okay before, will wait for a go signal before trying 3.10.32+ again… (The few things on my SQM todo list will work just as well with the 3.10.28, so I really just wanted to see whether the TX hangs would be gone with 3.10.32, but they still remain...)

	All this sounds quite promising…
