N770 behaving weird

A couple of years ago I got a second hand N770 from a friend and I have been using it frequently and satisfactory. However, for the last couple of mounts it is starting to behave weird, as if it is degrading.



Symptoms:

• It is very difficult to establish a WiFi connection. Most of the times it wrongly reports that no APs are available, or fails connecting to one. Sometimes it reports nearby APs with a very low wignal while in fact the signal is very strong.
• Connection failure is reported after 5-10 seconds, long before a potential DHCP timeout. Once a connection is established it is stabl and behaves normally.
• Spontaneous reboots, most often when connected to the charger. Sometimes I connect it to the charger and it reboots within a couple of minutes. Sometimes it just keeps rebooting.

I suspect the battery but given the charger-reboot issues I'm not sure enough to buy a new battery,



Does anyone recognize this behaviour? Any tips?
