|First of all I would suggest to flash the latest firmware to your linksys router. This mostly helps.|
DHCP is quite good for using it with client computers.
Static IPs are normally only used for servers or ip printers and something like that.
If DHCP isn't working properly, it shows to you, that something went wrong in your network system.
To use static IPs isn't the best solution for such problems and mostly woun't solve the existing problem.
Please send a reply, if you solved the problem !!!
