Cisco Routers :: SRP 527W - Wireless Connections / Unable To Update Firmware

I have recently acquired one of these routers. I thought, being a Cisco product, it would be the bee's knees. It is not.  After finally getting the network set up - no mean feat, although I do not claim any expertise, but had to resort to some other network management software to finally get it all running - the router drops either the WAN connection or the wireless connection many times a day.  The laptops often show as being connected to the network/router, but are unable to access either the internet, or the router via the browser. Re-booting the router is the fix, but, hey, I can achieve that sort of performance with any old $20 router - none of my old Net gear routers was this troublesome.
 
The permanent fix would seem to be a firmware upgrade, but guess what?  The only options available under the "Administration" tab are time setting and switch settings - no firmware upgrade. The supplied firmware is 1.01.09(001) Apr 7 2010.  Why these products are supplied, as new, without the latest firmware installed beats me, but there you go.
