I hook up my laptop to the same modem, same port, using the same cable and I get 17mb down. I have ruled out iptables, nics (because same result on both nics), cables, cable modem(with a brighthouse rep) any suggestions would be greatly appreciated. Thanks. ********************************************** JohnStanley Writes: Maybe trying the vender specific drivers for the Nic Card in question on the CentOS Server may solve the problem. Or a possibilty is if your Bonding or teaming the nics there may be configuration issues in the way you have them set up. Try just one Nic card by itself with out Bonding. You can use "miitool" to set or force the transfer rate of the nic in question; see "man miitool" Since you do say you have dual nics try them both separtly like I stated (Without The Bonding).
