XAV5501 problem after PC standby
Hi,
I've just bought a XAVB5501 pack, with 2x XAV5501. I plugged one near my cablebox, and the other one in my bedroom to a Desktop PC (let give the name PC1, that runs Seven 64x). It works fine, connection is good (Rx and Tx > 100Mbps).
But I have a very bad problem. Every time my PC1 goes to standby, when it wakes up the connection is lost. The XAV5501 always stays in standby mode. So I need to desactivate my network card on PC1 (it is an Intel 82579V Gigabits), wait a little, then reactivate the network card. This way the XAV5501 "see or receive" wakeup event, and the connection is established.
So I know that problem is about standby/wakeup. What I've already done:
-update both XAV5501 firmwares to lastest (v0.2.0.9CE)
-update network card to lastest driver from Intel
-turn off every thing relative to economic mode in my network card (there's a lot of option in network card driver panel page under Seven)
-turn on Wake On Lan/Magic/Link on my network card, but I don't think it could solve anything, because my problem is to wakeup the XAV5501, not my PC
I'm here, and don't know what to do now.
Please can someone give me a solution?
Thank you very much in advance, and I apologize for my bad english.

- Count me in on this one. I also have a problem with the XAVB5501 adapters going into standby mode and would like to disable this feature. Is this possible with the current setup? If so could someone let me know how.
Thanks :) - Hello,
just to let you know that I let it down. I've return back my products twice, always the same problem.
I've changed for another brand, and now it works fine. I think netgear can works good but may be have incompatibility with some hardware.
Regards, - Thanks for the info.
However I haven't got to the stage where I want to return them yet as I'm pleased with the performance I'm getting and find them really easy to setup. It just seems to me that these "standby" problems will disappear if the units never go into standby mode. I previously had some Comtrend adapters (!) and they never went into standby mode...probably because they didn't have one :)
What I would like to have is the ability to customise the standby mode, including turning it off altogether. Please. - Ok but as far as I know, you can't turn back sleep mode.
That's why I've changed, because performance was good too, but when it wakes up ... - I observe something I can not explain.
When I just start uploading from the PC to the mediaplayer I get a rediculous speed of 270KBs, which tends to slow down over time. However when I first do the opposite and download from de player to the PC I get 7MBs. After downloading from the mediaplayer for some seconds than stopping it and than start the upload from the PC again I do get a reasonable speed of 1,9MBs and the speed is maintained.
Anybody there who has a valid explanation?
:cool::eek: - Add me to the list of persons with connectivity problems after standby. Have the XAV5501/XAV5504 kit with HTPC, blu ray and AV receiver connected to the XAV5504. The XAV5504 resumes from standby when I turn a connected device on. No problem there. However, the IP address assigned by DHCP to the connected devices is wrong. Instead of the standard home subnet of 192.168.1.x the adapter often assigns a different subnet address (sorry, I haven't made note of the incorrect address.) This requires unplugging and replugging the XAV5004 adapter. Normally the adapter then assigns the proper subnet and my connected devices operate fine. This seems to be intermittent; it will work fine for several days then require an unplug/replug. The next time this happens I will make note of the incorrect subnet address and post. Maybe this will help isolate the issue. But clearly this is a firmware bug that Netgear should fix.
- Sorry, I misspoke in my earlier post. It is not the subnet address, of course, but the IP address that is being improperly assigned by DHCP in my XAV5501/5504 kit.
I've had another instance of IP misconfiguration after standby. The IP assigned by the powerline kit to my blu ray player is 169.254.197.41. Subnet is 255.255.0.0. A trace on the IP # found nothing. My router IP (from comcast) starts with 66.177 so I know it's not coming from the router. Unplug/replug fixed the problem temporarily.
Any ideas? - Ok I found more info. The 169.254.x.x address range is called "link local". Basically, when DHCP fails modern networked devices default to a useless link local ip address. Read more here.. I can see these dummy addresses on my blu ray player and AV receiver. My HTPC (Win 7) hides the address and simply fails to connect to the network.
Since unplugging and replugging my XAV5004 solves the problem (temporarily) there is definitely a firmware bug with standby mode. When awakening from standby it fails to negotiate properly with DHCP. By design any connected device simply defaults to a link local IP. Only a cold reboot (unplug/replug) allows DHCP to work properly.
Unfortunately I can't return my unit so I patiently wait for a firmware upgrade. This is my first Netgear equipment that has let me down so thoroughly. Love the connection speed, but....

Open a ticket at my.netgear.com and explain exactly what you posted here. This forum is primarily customer driven and not monitored by Netgear support staff. Maybe with your findings you can help the engineers to correct the issue with a firmware update.- I have opened ticket and will advise group of Netgear's response.
