wifi problem xz1 compact

Phone is useless. Cannot use at home for more than couple of minutes before wifi goes slow and keeps stopping. Have reset phone.deleted caches history etc. Switched off router. Nothing works.

After the recent 47.1.A.12.235 Update, I recently encountered this issue. All previously remembered wifi connecitons fail to be seen at all when in range. Manually removing/reauthenticating them does not work either, as they are just not seen at all. Has anyone found a workaround for this? There is an article saying to reset the wifi router, however this is not for just my home wifi, but my work, at my in-laws, etc, so that wouldn't be viable for me to fully resolve...
