I notice that sometimes after flashing a new ROM (or a ROM update), my signal strength may vary. Some days I might show great bars and others I have none (even with my network extender). I'm also constantly flashing kernel updates (usually the latest Franco). So the question is...does signal rely on your radio version, your ROM, your kernel, or all three? For those that know, does one of those items typically have a greater bearing on strength than another?
