Wireless lockup problems

[takeawaydave]

Hi been encountering a problem where my laptop as well as desktop start to not be able to access the network and rebooting my rt-ac66u (with 3.0.0.4.372.30_2) appears to solve the problem. Not sure what its related to nor how to proceed in narrowing down the problem.
symptoms are varying:
1. sometimes a ping to router is possible - other time no route to host.
2. ssh router on to router mostly doesn't work when it does its slow and a slow sesssion ensues.
3. a nslookup to external website e.g. nslookup google may resolve some times not.

I don't see packet errors on the local adapter. and the wireless signal has max bars (not bad reception). Using the 2.4 Ghz network.

I suspect this is the start up log not the one capturing any problem but a guru eye may spot something

Recently set dnsmasq up not sure if this is to blame.
Thanks for looking and any advice on troubleshooting appreciated.

Seems to be a problem with dnsmasq. When I reconfigure the local laptop NIC away from dhcp by giving a static address and DNS as a fixed 8.8.8.8 the internet connection resumes.

any ideas what could cause this ? otherwise it's back to using a localhosts file.

Last post I made was rubbish nothing to do with dnsmasq. Looks to be more like the wireless settings.
Most wireless clients (ipad, 2 x iphones) are ok, mac pro and macbook giving same wireless trouble through.
I have connected macbook to the router using an ethernet cable and i have a fast stable connection.

Could the "b/g Protection" cause such a problem ?

Since your issue is Mac-specific, I would have a look here:

Thanks Merlin - That was a great help and I enabled the 80211d broadcast for w0 and no problems have yet arisen.
I was also having a drop between my Linksys AC wumc710 bridge and rt-acc66u so I have also enabled on w1 to see whether there was the same root cause here.
