try playing with the MTU settings my problem was solved by playing
with it , try changing the device name accordingly
eth0 Link encap:Ethernet HWaddr 00:1F:16:36:49:A5
inet addr:XXX.XX.XXX.XX Bcast:XXX.XX.XXX.XXX Mask:XXX.XXX.XXX.XXX
UP BROADCAST RUNNING MULTICAST MTU:1500 <<<<<<<<<<<<
An example command would be like:
# ifconfig eth0 mtu 1300
And, if this solves your problem, then set the appropriate MTU in your
/etc/sysconfig/network-scripts/ifcfg-eth0 as:
DEVICE=eth0
MTU=1250
