Hello, I have the latest firmware 1.0.2.04 on R7800 and have an issue where my wifi client cannot access servers on lan on the same router. I found suggestions about firmware resets and turning off the router but that doesn't help. It seems that 50% of the traffic gets blackholed somewhere. LAN-LAN works just fine. WiFi-WiFi works good as well. But WiFi-LAN doesn't want to work.. Any ideas?

evel I'm using Kong Mod from myopenrouter.com. It's a straightforward process on how to replace the firmware (just look at the latest article). For VLAN tagging, you'll need to create a VLAN on eth0 (default WAN) interface (Setup->Networking) and assign a newly created port as WAN port on the same page. Once you're online - you can easily do the rest (wifi, services, etc). WIFI->LAN works right away. Thx, Mansus.

storm1985, thank you for your input. However why would it "should" work? Ping runs over icmp protocol which runs over udp. HTTP, SMB run over TCP/IP. For example, I'm trying to RDP to another PC. And the first phase is successful - e.g. it prompts me for the credentials. However after credentials are entered the connection fails within some seconds with an "internal error has occurred". But accessing the services on the router (e.g. router gui) works just fine. Ergo it does seem like a firmware issue to me.

  I am having the same issue.
  
  I have multiple wireless devices that cannot access LAN resources.
  
  I can ping the wired resources but:
  
  1. Cannot access a wired NAS device from wireless devices. Wired can access it fine.
  2. Cannot control a wired Roku3 from my android phone over wifi
  3. Cannot RDP to my wired desktop from my wifi laptop
  
  Again, ICMP is fine. Anything else will sit and spin until it times out.
  
  It was working fine until I updated to the latest firmware. 1.0.2.04
  
  I also starting using it with a fiber connection and setup a VLAN bridge group.

    evelI have opened a support case with NETGEAR and they have collected the data. They are going to reproduce the issue in house and hopefully fix it or come up with a recommendation.
    
    Thx, Mansus.

None of those are using Guest?

It shouldn't be happening, the only thing to due is reset to defaults and or try another FW

  Nope. None are using guest. Actually I tried guest wifi with enabled option to be able to see other clients but that didn't help either.

    Did you set up home group if you are on Windows OS? Anything user password protected individually? Easiest thing is setting up
    home group to share things such as files, pictures, music, etc.
