stubblejumper t didn't show up so I entered its address 192.168.254.254. ASIAIR said it couldn't find that device.
Did you first connect the tablet's WiFi radio to the Vonets network?
Until you finish configuring the Vonet to join the home network, the only way to reach it and devices that are connected to it, is to connect your tablet directly to the Vonets' WiFi radio.
On iOS, just go to Settings > Wi-Fi and the Vonets should appear in the NETWORKS box. Remember to change it back after setting up the Vonets.
After configuring Vonets as an extender to your home network, check your Home router's device tables. Vonets should be one of them. If not, the Vonets has not suceessfully connected to the home network.
If the home network sees the Vonets, look for the ASIAIR in your home network too. If it is not there, but Vonets is there, the ASIAIR is not properly connected to Vonets. There are a couple of ways to check this:
1) on the ASIAIR RJ45 connector, there are two LEDs. One is the activity LED and should be blinking sporadically when it exchanges keep-alive packets with the home network. If this LED is not lit, the ASIAIR is not seeing the Vonets. The second LED is a Gigabit indicator. It is constantly lit if the Vonets connected to the ASIAIR LAN connector is Gigabit capable, and constantly off if the Vonets is only capable of 10/100 Mpbs.
2) connect your tablet directly to the ASIAIR WiFi network ("hotspot"). Click on the ASIAIR Settings page (the icon that looks like a WiFi Icon). Look down the list to "Wired Ethernet." It should say Connected. If not, ASIAIR does not think it is connected to Vonets. With v2 of ASIAIR, the tablet needs to be within a foot or two of the ASIAIR, especially if you live in a neighborhood that is WiFi congested.
If ASIAIR says it is connected to Wired Ethernet, tap on the extra information (on the right of the "Wired Ethernet" item, and ASIAIR should bring up the Details window. It will show the IP Address of the ASIAIR. You can use this address to connect to the ASIAIR if the ASIAIR app cannot find the ASIAIR device by itself.
If your home router can see the ASIAIR, you can also note down its IP address from the router than from ASIAIR's settings, and use that address to connect. This should be the same address as the one found in ASIAIR Settings. I have found ASIAIR's networking to be less than reliablewhen trying to discover ASIAIR devices (and that is being kind). When those occasions occur, you need to use the direct IP addresses.
If all else fails, just trash the Vonets, and use a quality device like the TP-Link and the GL.iNet travel routers instead.
If you finally succeed in connecting (Vonets, or TP-Link, or other routers), I highly recommend that you assign a Reserved Address for the ASIAIR in your home router. This associates a fixed IP Address to the MAC address of the ASIAIR. In the future, this IP address will be sticky and you don't have to recheck for the address either from ASIAIR or from your home router. Write it down on a piece of Gaffer Tape and stick it onto the ASIAIR.
