ASRock z77 extreme6 - Slow LAN Tags: Motherboards LAN ASrock Last response: July 13, 2013 6:35 PM in Motherboards Share y2hbk January 11, 2013 12:10:43 AM Hey everyone. Just built a new machine with the mentioned MoBo and I have horrible download/upload speeds. If I plug my old system back in which had an Asus Sabertooth x58 - everything is fine. I updated the broadcom driver from ASRock's website - no change. I also tried installing their XFast LAN thing - no change. Any recommendations for what to try next?

I would uninstall, restart, then run a registery checker. y2hbk January 12, 2013 1:20:21 AM I removed it and ran ccleaner after a reboot. Saw no change. I went ahead and reinstalled Windows 8 since I hadnt done much on the new machine yet. Still slow. CCleaner, for instance, took about 2 minutes to download, its 4MB. On my old rig, I tested downloading it and it was done in about 10 seconds. As I navigate to web pages, it takes forever for the contents to load.

I get .82 to 1 meg down with this new Extream4 mobo. Freaking sad... Did you ever find a resolve for this? Thanks, John pede69 January 25, 2013 2:29:31 AM OK guys I solved the slow lan speed issue. Following is what I did. Simple really... One may have nothing to do with the other but wow... First I went into the Extreem4 bios and changed the setting in the OC area at the bottom underneath where it shows the ram timing, form Auto to XMP. Then I uninstalled the XLan Fast program. Wow... my computer itself is lightning fast now (MUCH faster than it was) and my download speeds are right up there with the other computers in my home. Do these two things if you have an Extream4 and you will be glad you did. Also, if you run across someone else having the same issues, please pay it forward and either tell them how to fix it or point them to this thread. Thank you,, John greekginger July 13, 2013 6:35:47 PM Just want to add...I had a similar issued caused by xfast lan...not sure how or why but removing it resolved the issue completely Can't find your answer ?
