A failing router tops my suspect list, and costs have come down significantly.
However, interference & signal drop out are also possibilities.
Experiment with channels 3,6, and 9. Observe if link is stable with good data rates.
Any new appliances or large heavy objects blocking antennas?
Are both laptops in the same room? (normally this is not a problem)
I do not know how to make changes, but I understand that the default transmission power lever is less than the max. than can be delivered by both ends (router & adapter). One of these days, maybe, I can confirm this as worthy of consideration - but I read it in another post.
Oh, check your router for parasites. MAC filtering limits who connects to the router. Encryption helps protect your data, but it is far from perfect.
