How many total clients are going through the netgear router on the 5 GHz?

I gave DTrack the images but they still would like the config file if possible.

There are typically 15-20 clients connected to that Netgear router during the day, including several mobile phones.  The clients are not all continuously active though.  The ones in my lab are idling in Windows most of the time.

I used the "Site Survey" feature of 868L to take a signal strength reading of the router 5GHz signals in my lab where the D-Link bridges are located.  The ch 36 signal is in the -63dBm ballpark, and the ch 153 signal is around -51dBm.  Not the strongest of signals, but considering there are 2 walls separating the NG router and my D-Link bridges, it's not too bad.  I also used inSSIDer Lite to gauge co-channel interference and overlapped channels.

Today I also changed the Netgear router 5GHz-1 radio from ch 44 to 36, and switched one of the two 868L bridges to connect to ch 153 instead of ch 36.  Will see if there is any change in wireless link drop behavior.  There has been no link loss observed from any of the three D-Link bridges since last Friday.  Not sure what led to the better behavior, though.

DTrack team has a netgear R8000 and they said they do see some connectivity issues so it may be some issue with the 2 devices working together. They are testing further this week with the R&D team.

I've saved a .CFG file for the Netgear R8000 router, but with admin & WiFi passwords intact, since I cannot change these without disrupting ongoing client testing.

Please PM me the email address to send this config file to.

If you can, please save off a router config to file and email that to me. Before saving off the file, removing any router log in PW or set "password" then save off. You can change the admin log in back after the file is saved. I'll send this to D-Link.

Thanks for the update!  Interoperability issues between Netgear R8000 and DIR-880L (and DIR-868L) is a good description of the problem.

Signal strength in the -60dBm ballpark for my D-Link bridges isn't exactly great, but is enough to sustain ~100Mbps downlink speed for clients attached to the 880L bridge.  I think the Comcast Business internet service in use maxes out at about 120Mbps downlink, so the clients are not seeing much speed loss over the 5GHz wireless link.

Since I really can't relocate that Netgear router sitting in the other lab, would it make sense to look into outfitting the 880L with higher gain 5GHz antennas?

"Possible that the distance is too far and the signal is dropped. With two walls and 50 feet, 5Ghz is effected by building materials."

However lets see if D-Link can find the main problem with between the two. I know that for mine, the 880L and 890L work. So there many an issue with the R8000.

Any chance you can swap in the 880L as the main router and use the R8000 was a bridge?

Just emailed you a .CFG file from my Netgear R8000 router.

I sent you a pm with my email address.

I don't think the R8000 supports bridge.  Also, R8000 has two 5GHz radios but DIR-880L has one.

I just sent the file to dtrack. Hopefully they can figure out what the issue is.

Have you attempted to get the 880L to connect to either 5Ghz radio. This is one thing I wish the 880L UI had in this scan results so you can see which radio and channels that a wireless source is using.  >:( Makes it hard to connect to Tri band routers with out some form of help on this.  ::)

I presume either 5Ghz radio on the R8000 will probably exhibit same behavior though. Just a thought.

I did try linking over ch 153 briefly earlier this week.  The link failure rate appears to have gone down noticeably ever since I moved the 880L away from one of the 868L bridges.  I just switched the 880L from ch 36 to ch 153 again for some test time with the higher 5GHz radio.

Totally agree on the dumbed down WiFi scanner UI in the 880L.  Nowhere near as useful as the one in the 868L.

Ya, ever since D-Link went to this new UI, we've really missed the wifi status and information seen from days of old UI.  :-\

Something I'd like to see forth coming in the new AX stuff.  ;) Would be nice to know what devices are connected to which radio, mode and channel and speed devices are connected at. Man I miss those features.  :-\
