Wireless start drop and connect every few second after SEP install
Created: 24 Oct 2007 | Updated: 21 May 2010 | 15 comments
I just install the SEP (unmanage mode) to a laptop for testing. However, it start to drop the wireless every few second and reconnect again.
I disabled the Network Threat Protection and the wireless started to work again. I checked the Traffic log and found that protocol Ethernet has been blocked
24/10/2007 3:07:56 PM Blocked 10 Incoming ETHERNET 0.0.0.0 00-13-CE-AF-F9-7C 0 0.0.0.0 00-16-B6-51-10-2E 0 jianan.lim INVIZAGE Default 1 24/10/2007 3:07:15 PM 24/10/2007 3:07:15 PM Block_all
I have no idea what kind of protocol is this as I cant find what protocol number is a ETHERNET would be.
If any one can tell me how to configure the firewall rules to allow the above connection that will be great.

Hello Jian,
I'll take a stab at this as I was having a similar problem, albeit with a desktop computer using a Belkin USB Wireless adapter. I initially had SSC 3.1 installed and installed SEP directly over the existing SSC deployment. Upon restarting the desktop, there were numerous wireless problems much like the ones you describe: My wireless connection would keep restarting, and each time it restarted, it would try and obtain an IP address. I uninstalled SEP, rebooted, and then re-installed SEP. After doing that, all other previous problems seemed to go away, such as problems printing to a wirelessly connected network printer and problems with sending outbound Internet email from Outlook 2003. As an additional item, I could not resolve the wireless problem. As a last resort, I also did a power cycle on my wireless router and sure enough, that solved that problem.
So, it is possible that it might not be SEP but that your wireless router needs to be power cycled. At the very least, it removes a variable from the list of possible suspects and helps to narrow down the cause to something related to SEP.
Hope this helps.

Hello Jian.
I have the same problem, just wantet to check if you've reached a sollution to the problem yet?
Regards Thomas.
No, that method does not apply to us.. it's a known bug in SEP.

Regarding AP/Router, i have one Linksys WRT54G and one Linksys WRT350N v2.
Same problem on both.
I just hope that Symantec adresses this issue fast.
Ick, i was just going to try WEP, thanx for the heads-up.
Maybe we should go for no encryption for the time beeing.
with MAC-filtering + local VPN ofcourse.
Hi Carsten.
Atleast for me, i am using WPA(TKIP) on my WRT54G and WPA2(AES) on my WRT350N.
Do you have any special rules regarding ETHERNET set in your firewall?
(I could not find any way to change the block_all rule and add ETHERNET rules)
My laptop is a Lenovo T60p v2007.

Ok, keep me/us posted.
I hope for positive results.
Hi.
Just wondering if that patch did anything positive in regard of wireless?
