One way flow using Internet Surfing
I have an issue where the EX6100 limits communications between wireless devices (laptop) and wired devices (desktop) to one direction. This occurs only while in internet surfing mode; switching to FastLane solved the problem. Bypassing the EX6100 and connecting directly to the wireless router (ASUS RT-AC68U) also solves the problem.
The laptop in this case is wireless, and it can fully interact with the LAN computers. Attempting to connect to the laptop from the LAN side fails with the famous error code 800700035. I can ping the laptops IP from the LAN, but not ping the name; this made me think it was TCP/IP related but not so. Switching the E6100 from Internet Surfing to FastLane solves the problem.
Using FastLane is problematic in my case as there is local interference on the 2.4Ghz band. Regardless of which FastLane option is selected - router to extender in 2.4Ghz or extender to device in 2.4Ghz - interference becomes an issue, so using the 5Ghz band is optimal.
I have this issue [error 800700035] in other forums typically tied to firewalls or NETBios over TCP/IP; but I'm pretty sure through experimentation it's tied to the FastLane vs Internet Surfacing function of the EX6100.
Ideas, suggestions, comments are welcome.
