Wi-Fi or iPad 1 problem?

We have a first generation Wi-Fi iPad, (32GB, 24GB available) on 5.1.1. We use it mainly for surfing the net and reading e-mails. When we are reading a Web page (eg. local paper) it will just go back to the desk top. You can always just open Safari again and go back to the Web page you were on or another one. Never does it on ehMac, or any of the other forums I use. Local paper and Facebook seem to be the worst. Seems to be doing this more and more lately. Could it just be the age of the iPad? I am just looking for possible actions to stop this from happening. Our iPhones, eReaders, and iMac never have Wi-Fi issues.
