I have problem regarding my wireless networking at my home.

And currently i'm using WRT54G v5 and Aztech 305e as Streamyx modem. Currently i faced the problem that my DSL led kept blinking like mad and suffered very frequently disconnection when i attached the cat5 cable from modem to my wireless router.

And sometimes , when i switch on the desktop power on which connected through wired line to router , the modem will blink blink again.

I wonder if anyone experienced same problem w/ me? Btw i've flashed my wireless router w/ latest firmware version 1.0.0.6 from Linksys

Help me ,i'm bewildered

No , DD-WRT firmware isnt available for v5
