Tech Q&A: Best routers, low airfares, Facebook privacy, dangerous cellphones and more

Cellphone dangers

Q: Every time I hold my phone up to my head, I wonder if it’s giving me cancer.

A: Like many daily activities, using cellphones has prompted some startling, albeit inconclusive, research.

Outsmart flight-booking sites

Q: I want to buy airline tickets for the holidays. Is it true that the airline sites track where you go online?

Do the online booking sites’ algorithms use this intel to change airfares? Whether they do or don’t, there are ways to browse ticketing options without anyone knowing who you are, and this technique may help your chances of landing a good price.

Get a faster router

Q: I need a new router. Which one should I buy?

A: If you spend a lot of time on the internet and you need a good deal of broadband, be on the lookout for multi-band routers.

Pro tip: No matter which router you choose, buy it outright over renting one from an internet provider, because you are certain to save money in the end.

End social media rants

Q: Certain family members are driving me crazy on Facebook with their political and stupid posts. How can I stop seeing the posts without unfriending them?
