It's been two weeks now.

Where I live, we had well laid roads but, because building of other properties continued, the final surface was not laid until a few months back it was the subsurface. Thus the lowered kerbs, ironworks, etc., presented a bit of a lump and required care.

They have now done the final surface, a lovely job in fine tarmac.

But the oddity is that I use a wifi relay and, since the final surfacing, it has improved transmission - from typically about 90% to almost always 100% as the unit shows. No other changes at all.

No relevance to anything else. Just my observation.
