I have a DIR-655 Dlink wireless router I am using to supply internet access to 4 mining rigs each running about 5 cards.

I am having troubles connecting to deepbit.net occasionally using phoenix miner. I will mine great for a few hours/days but eventually some of the cards go offline and never come back on. This is always preceeded by a "deepbit.net unavailable" type message...

Would It make sense to optimize port 8332 or my router in the QOS/traffic shaping section?

I have read phoenix miner is no good at re-connecting from downed internet connections (I am using the version available in linuxcoin v0.2a, not sure what version of phoenix it is, perhaps I have to upgrade?)

Any suggestions are appreciated!
