P55A-UD3P: my internet sometimes fast, sometimes slow, help ??

[roy_harlie]

hi all,

i want ask..

1st thing 1st

2 month ago, my mobo P55A-UD3P (rev1.0)
play game n play hd movie, often hang.. i change to store i bought

now my mobo P55A-UD3P (rev2.0)
the hang gone, but ..


if my internet sometimes slow, sometimes fast, why?

sometimes when slow, i click diagnose, then windows repair the problem : default gateway not found.. ?
(not every i click diagnoe, repair gateway not found, only sometimes)

sometimes when slow, i click disable on local area connection, then enable again, the internet fast again, but after few minute slow again.. ?? (randomly in minute fast again, randomly slow again)

sometimes i uninstall realtek network driver in device manager, then install again, after that fast, but few minute slow again.. ?? (randomly in minute fast again, randomly slow again)

i have 2 isp conecction

eg : isp 1 & isp 2
usually i use isp 1

when i use isp2 still slow, and fast randomly

when other pc i connect to isp 1 and isp 2 no problem with fast n slow..

mean the problem in pc not in isp right ??

if use speedtest.net the upload n download speed normal (fast)
but when browsing slow..

it's a bad lan card or cause other thing?

my pc never shutdown, even 1 minute..
whether it is possible the lan card heat, and cause slow?

maybe other setting in bios?

anyone know why ??


my spec :

i7 860
g.skill ripjaw 4gb
5850 toxic 1gb
mobo gigabyte p55a-ud3p (Realtek RTL8168/8111 PCI-E Gigabit Ethernet Adapter)
wd caviar black 1tb samsung f3 1tb
corsair hx 650w
7 32-bit

thank you very much..

I have two pc's and the lower spec'd one seems faster than the other, go figure. So I have experienced the same thing as you from time to time. have you tried resetting your modem/router? Update the lan drivers?

Hi and welcome to the Gigabyte Forum.

You have done a lot of the diagnosis yourself already in that you have eliminated the ISP and narrowed it down to a local fault.

Do both computers connect via the same router?

Have you tried changing the LAN cable to the computer?

Have you tried rebooting and does it have any effect?



Hey you're getting a bit fast fatman!

Lol DM..was just having a look around to kick a few tyres hahahaha and I have had similar issues to the OP. Just thought I'd throw in my 0.02 worth .

Have you tried swapping the routers over to see if it's a router problem?

already swap, still same..

if there problem in mobo? or comodo firewall ?

[Dark Mantis]

Most probably it is software. Try disabling the firewall and leaving just your AV running and see if that makes a difference.
What AV are you using?
What browser are you using?
Can you please update your profile so I know where you are located?

Have you tried running http://www.speedtest.net/ or similar to get a good idea between your pc's? You could get a ethernet card to try in your machine and disable your onboard lan? Just to rule out the mobo???
