When should I replace my wireless router?

I own a NETGEAR N600 Dual Band router: model WNDR3400.
We've had this router for 2 years now, it works fine. But sometimes, every year since we've owned it, the internet has either went down for a day, or occasionally even the router. We have Comcast XFINITY double play. We get 25-27mbps download, and a 3.4-5 upload speed.

We got this router because me and my brother play XBOX and PS3 at the same time online, while our parents stream videos online. My iPhone 4S once every two months will randomly pick up the signal for 5 seconds, drop it. This will go on for 2 days.
We reset it once every 3 weeks. Once, we changed the security password and it ran fine for 3 months.
Lately, the speed has been slowing down drastically!

How to use instagram while vacationing in another country?

I'm going to Uganda and Kenya in July. I have an iPhone 4S with Bell. I'm staying in a hotel that will have Wi-Fi. Will I be able to keep my phone so I don't get calls or texts but can still use Wi-Fi to upload pictures to instagram or my status on Facebook?
How would I do that? On airplane mode, can I connect to Wi-Fi?
