Tom62e I use the ASIair Plus and I haven't changed anything other than updating to the latest firmware.
Hi Tommy,
Remember that for WiFi to work as specified, both transmit and receive directions will need decent signal to noise ratio (it is not signal strength that matters, it is SNR). So, it is dependent not on just how strong the WiFi signal from the ASIAIR is, but how strong the other WiFi signals in your neighborhood are.
If you have an Android tablet, there are a number of WiFi tools that will show what the 2.4 GHz and 5 GHz bands occupancy look like. See if ASIAIR has chosen a WiFi channel where at your house (signals from you and neighbors) is congested, when measured at the location of the ASIAIR. Mesh routers in the neighborhood can be very troublesome, since some of them put out very strong signals, and some also blanket the entire band. I can easy see the mesh router of a neighbor two doors down from me in an area with 2 to 5 acre lots.
You can change the Raspberry Pi configuration to use a different WiFi channel, away from the loudest interference. This config file (channel and band) used to be available in the early ASIAIR v1.x days in the Boot volume of the microSD card, where even Macs and Windows can edit them, but you may need to ssh into the ASIAIR nowadays to change the WiFi config (check Google for "ASIAIR ssh").
Unlike other systems, I do not see an easy way to change the WiFi channel in ASIAIR's Settings. INDIGO Sky's WiFi channel can be changed right from INDIGO own web server, for example:

Another way is to not use the ASIAIR hotspot. Instead, if you use station mode, ASIAIR will move to your router's WiFi channel and cohabit with the router.
The only easy and reliable way to fix it is to not use ASIAIR WiFi at all. Connect the ASIAIR LAN port to either your home router, a WiFi extender, or directly to your tablet through a WiFi dongle.
