If you're using a true IP camera, you might consider wiring it to a much more powerful bridge. My 'PatioCam' is wired, which I did after much frustration with crashed wireless connections, but my 'StreetCam' is wired to a bridge:

Both camera are now StarDot Netcams, which is probably overkill, but they are very reliable, and they stream via their own DynDns addresses.
VWS was my weather software when I began using a webcam, and I used ImageSalsa for processing the static images. The images are still processed this way after the StarDots ftp them to a weather computer directory. I've largely given up on continuously connected wireless via adapters. This computer and a companion are connected via another wireless bridge on the 5G band,

Just a different approach to consider. YMMV.
