problem with ethernet controller D-Link.

have Centos 6.2 and 2 ethernet controller: integrated and PCI D-Link(520 or 528)

[root@S /]# lspci |grep Eth
04:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168B PCI Express Gigabit Ethernet controller (rev 06) #integrated
07:00.0 Ethernet controller: VIA Technologies, Inc. VT6105/VT6106S [Rhine-III] (rev 8b) # Dlink

[root@S /]# dmesg |grep eth
eth0: RTL8168b/8111b at 0xffffc900050a4000, c8:60:00:56:0e:26, XID 0c900800 IRQ 36
eth1: VIA Rhine III at 0xfe400000, 84:c9:b2:7d:df:57, IRQ 16.
eth1: MII PHY found at address 1, status 0x786d advertising 05e1 Link 45e1.
r8169: eth0: link down
ADDRCONF(NETDEV_UP): eth0: link is not ready
eth1: link up, 100Mbps, full-duplex, lpa 0x45E1
eth1: no IPv6 routers present

The problem is that after a few hours of network card D-Link (520 or 528) begins to fail (increases dramatically slows down the network and ping)

[root@S /]# ping 192.168.1.254
64 bytes from 192.168.1.254: icmp_seq=2 ttl=255 time=96.0 ms
64 bytes from 192.168.1.254: icmp_seq=3 ttl=255 time=95.0 ms
64 bytes from 192.168.1.254: icmp_seq=4 ttl=255 time=93.9 ms
64 bytes from 192.168.1.254: icmp_seq=5 ttl=255 time=93.0 ms
64 bytes from 192.168.1.254: icmp_seq=6 ttl=255 time=91.9 ms
64 bytes from 192.168.1.254: icmp_seq=7 ttl=255 time=90.9 ms
64 bytes from 192.168.1.254: icmp_seq=8 ttl=255 time=90.0 ms

and so up to 10 ms, then back up to a maximum value (about 100 ms) and down

what could be the problem and how to fix it (tried different drivers, a problem everywhere)?

after a reboot, or restart the network, system is running fine, but a few hours
