We have several hundred Vera-3 Gateways installed in apartment buildings. We have 5 new cases of strange interference, reported by techs and maintenance people.
The tenant’s router is always a D-Link AC1750 WiFi Router DIR-866L -all 5 occurrences. We are running the Vera-3 on our own LAN, connected to our own WAN. The scenarios is as follows: We have trouble with a series of devices talking to the gateway (up to 15 at a time), but when the router is restarted, this instantly goes away. Plugging the router back in does not immediately scramble the signal, and the network works for another week or so.
It is possible that the CAT5 cables for our network and the COAX for the cable TV company run close in chases in the hallways, but would this cause an immediate return of the signal if the device is powered down?
I have yet to get on site with a spectrum analyzer to vet this issue.
I haven’t heard of anything like this, but I’m not entirely clear on what your saying.
Are you saying that a Vera 3 is losing touch with Z-Wave devices(interference on 908MHz radio frequency)? Or, are you saying that multiple Vera 3 units become unreachable via TCP/IP?
I’m assuming the former, Z-Wave device loss. The D-Link router should not interfere with 908MHz, but you’ll need the spectrum analyzer to verify. It could interfere with the Vera 3 WiFi, but I would expect that you turned it off. No?
Please do let me know what happens. I’m very interested in this issue.
I would think that the closeness of the CAT5, and Cable has nothing to with e issues being encountered.
I suspect this issues is generated as a result of a network issue…
When the D-link router has an intermittent communication issues over your WAN, Vera’s is interjecting itself (actually the router is finding Vera) and then obtains the DNS from Vera which results in your scenario. Consequently when rebooted, this is automatically resolved.
There is a design issue with Vera as it exposes itself on its assigned WAN port and do some reading below.
For me, it only surfaced when I switched out my router (Linksys DD-WRT) for a new one (UBNT). The slight difference in DHCP response time of the router was enough to bubble the issue up.
