If your Samsung Galaxy S5 may not find or be able to connect to a specific 5Ghz wireless network, you may want to check which channel the network is operating on. The S5 has problems when trying to connect to DFS-channels (Dynamic Frequency Selection).
DFS-channels are basically every channel from channel 52 and up. Try setting your AP to a channel between 36-48 (inc.), and then try reconnecting your S5.
Try downloading octy's GPSopt application. It's available free of charge at Google Market.
It resolves the slow signal acquisition of the Samsung's GT-i5801 (perhaps on other phones as well). I use it together with GPSstatus (also available at Google Market) and no longer have GPS signal issues.
While not officially supported, it is possible to have Adobe Flash on your Android 2.1 (Eclair) device.
