Am on Zuku service is excellent.
Am not sure how your connection is:
From the Outdoor Radio I have an indoor unit (white in colour) it has power and two connections on one end, for the Outdoor Power & the other connection for your machine/Laptop. On My case it connect to the Wireless router for access around the compound.
My router also has 4 cable connections that can be used by devices with no wireless cards.
Please advice how you have connected the devices since from my little experience when the radio(outdoor unit) reboots then your connection takes time to resume hence downtimes experienced.
Well at times am not getting 95% guarantee on the link. When its slow am at 60%.
One more common problem is the end user; the link registers with the initial device (PC/Laptop) used. If you happen to switch devices then you will have to ask support to re-register the second device - abit annoying but do sort this install a . ( this is the reason I have the Wireless router in place to help resolve this problem)
Contact me offlist I will assist.
