Hi Sarah,
I've used Maperitive (http://maperitive.net/) in similar situations to
download OpenStreetMap map tiles and store them in a local MBTiles
database, from where QGIS can load them very quickly!
Rough steps are:
1. Decide on your web mapping
2. Set the bounds using UI, or running this command (edit min/max Lat/Lon):
set-geo-bounds 96.1,19.2,97.7,22.4
3. Export to MBTiles (edit min/max zoom and path):
generate-mbtiles minzoom=5 maxzoom=14
file="C:/Projects/Test/Southampton.mbtiles"
4. Load the MBTiles file into QGIS!
This still requires an internet connection to download the data, but the
process can be left running overnight etc.
Cheers,
Andy

Hi everyone. I'm working on a project based in the Azores and wondered
if anyone knew of any reasonably good free topographic base maps I can
download, strictly for non commercial purposes. At the moment, I'm
trying to use the OpenLayers plugin, but I have a VERY slow internet
connection which makes OpenLayers or WMS frustratingly slow to load.
Thanks in advance for any ideas, Sarah.
