I recently spent 6 months in Mexico
with no security problems. But pretty much the same as along the California
coast, with Marina and other paid services plus open relays. As already pointed out, as long as you use an https SSL secured website, there shouldn't be a problem. For email
, be sure that your webmail uses https and also does an encrypted signon-I am surprised to see that some still don't. Better is to get an SSL POP3/SMTP account (or 2) from Gmail, which are also encrypted. Better because with crappy wifi signals the lower bit rate than webmail is a real advantage. VPNs are the ultimate, but again, there will be a lot of times you want to communicate with marginal signals.
As far as what to use as a secure browser, I recommend Google
Chrome. Their architecture uses one process per tab, so wifi problems that occur with one tab do not close down the whole program (like they do with Opera, which I am using now).
And of course you need a good external wifi receiver. Many use an Engenius EUB-362ext or an Alfa (not the n version) as a USB adapter. You can move them outside on top of your dodger
for a good view, and they also accept an external antenna
. Lot's of others out there, but these are also cheap
. Anything beats a builtin laptop antenna
Have fun. BTW, there are also internet
cafes, but these range from good to dangerous, OK if you can bring your own laptop
