Anyway, the lovely people at Simplicity International have sorted out our wifi problems and I'm giving them a plug because they were very good. When we changed Daughter's bedroom for the office we moved the modem to the new office and my writing place ... which is really a dressing room area, was the only one to suffer.
Husband has tried twice to get some sort of booster in to work with the existing modem but they resolutely refused to speak to each other. He was delighted that Simplicity's engineer had to make several trips because it wasn't straight forward so I have zippy internet service, and Husband has saved face.
Simplicity cover Bangkok, Pattaya, Phuket. They came the same day we called. They were very reasonably priced and although the engineers English was basic, they rang their office and someone with excellent English explained the problem to me.
Now, I haven't written today. I'm feeling bad (for not writing and bad tempered - for several reasons). I really should write even if my mood makes me resistant.
