IMO the best performance, reliability and security is derived when you use WPA-PSK/AES

IMO there is no reason to use WPA-PSK/TKIP unless the wireless client does not have the AES support option and if using WZC under Windows XP/SP WPA-PSK/AES is natively supported.

Why? Because AES functions/processes at the chip level so it is significantly more efficient with the added bonus of being much more secure than TKIP encryption.

In the unlikely event you are finding that AES is slower than TKIP it is probably due to some OS issue related to an LSP process. LSP stands for Layered Service Provider and LSP processes are frequently attacked by malware of one kind or another.

Lets just hope they don't break something else while fixing the firewall.
IF you have not already done so it IS very important that you email Belkin [usnetsupp@belkin.com] to complain that the SPI firewall BREAKS your system and request a firmware fix -- make sure to state that you do not feel that you are getting value for your money or the security protection expected if you have to disable the SPI firewall to get the functionality desired.

When emailing Belkin it is important to provide;
Model number and Version
Serial number
Date Purchased
Firmware version

The more people that email Belkin complaining about this issue the better.

I recently purchased the Pre-N from Costco, after reading some fabulous performance reviews on the web. I've got some Macs with built-in 802.11b cards (Airport), including my Titanium Powerbook with it's famously weak built-in antennae.

After trying the Pre-N with my Macs, I was pumped -- what an incredible jump in performance and range, even with the 802.11b cards! So I knew this was the wireless router for me. But alas, I had a new problem: my Cisco VPN client would connect to the office, but not work properly (pass traffic) on wireless or wired. I googled all over the Net, and found out that if I upgraded to the 2.01.02 firmware, it should resove that. Upgraded, and now it works.

is v.1002 what you mean by v2 (as opposed to v.2000)?

I have not read through this entire thread thoroughly, but I just want to say that my Vonage service works fine.

I did have some trouble with my alarm system's "kiss off" when trying to communicate with the monitoring center, which resulted in mutliple redial attempts and finally display of 'FC' on the keypad (or 'comm.failure' om 2nmd keypad).
This is apparently because the data is being transmitted
too fast to be fully understood.
I did some research and suggested to my friendly alarm installer that a "4+2 format" might help.
We ran a test (by temporarily programming my keypad with another account number that belongs to someone who has an older alarm that uses 4+2 and it worked on the first attempt. He is coming by tomorrow to reprogrammy unit; seems every zone has to reprogrammed (and re-tested).

The strange thing is that I hardly ever had problems with the current transmission format 'Contact ID' up until
a month or two ago, even though I had Vonage for years and have had this alarm for a year now.
Interestingly someone else experienced the exact same problem, where it stopped working about a month or two ago.
I will ask Vonage again if something was changed.

The Vonage technician (before I found out about '4+2' by googline even more and by testing it with my installer later that day) gave two possible reasons / solutions:
One was correct in that "lowering baud rate", which essentially comes down to switching to '4+2' format)
The other was grasping at straws at electromagnetic interference of large devices (microwave garage door opener) interefering with transmission over the WIRED telephone line .

I have a feeling Vonage changed something recently, but I don't know what.

The '4+2' format adds 7 seconds to the signal transmission time to the monitoring station, but that isn't a big deal; I doubt the burglar is going to stick around with a very loud siren ringing and a police station 1 minute drive away...]]> http://www.dslreports.com/forum/remark,14419171 Thu, 22 Sep 2005 09:58:20 EDT Re: Pre-N and VOIP woes http://www.dslreports.com/forum/remark,14410423 mozerd :

3) As far as I can tell, v2 of the router adds the firewall and v1 did not have it at all. So it is no more insecure as running the original v1 (which I have as well).
The F5D8230-4 version 1000 series, has from its release, support for Stateful Packet Inspection [SPI Firewall] and Network Address Translation [NAT - also a form of Firewall]. The version 1000 series did not provide security logging of value where anyone who understands how to read the output could make an intelligent assessment of the traffic being logged. The QoS implementation on the 1000 series works well for me [VoIP specifically]
The version 2000 series of the F5D8230 improves on the logging -- however I have not had the time needed to fully asses its merits. My tests so far also show that the 2000 series of this device is [30% +/- 5%] slower than the 1000 series.

1) It prevents DOS, SYN, UDP, etc.. floods and attacks. That is pretty cool, except it is screwing up VOIP. Ironic that this router has a QOS setting that smooths out VOIP yet the SPI firewall kills it almost completely.

2) The NAT functions on the router are protecting it as well as just about any other run of the mill router out there, even with the firewall off.

3) As far as I can tell, v2 of the router adds the firewall and v1 did not have it at all. So it is no more insecure as running the original v1 (which I have as well).

The SPI firewall is dropping out UDP packets as a DOS flood. You can look in the log file and see it. It is highly annoying as v1 of the pre-n router did not do this, at least not for me. I can also confirm that you must reboot the router after disabling the firewall or it won't work. Additionally, putting the voip adapter in the DMZ doesn't make a difference, reboot or not. I also updated to the 2.01.02 US version and it makes no difference either. Here is the log for any one interested:

On a side note...I did some speed tests through speakeasy's site before and after I switched out the routers (this belkin replaced a dlink) and saw marginally higher throughput... by about 10kbytes/s on download).]]> http://www.dslreports.com/forum/remark,14377809 Fri, 16 Sep 2005 13:13:56 EDT Re: Pre-N and VOIP woes http://www.dslreports.com/forum/remark,14377729 texxsharkk : Honestly, I can't really explain it, but I was having problems similar to you for a while and I really thought it was the router. I really never did much other than a series of reloading firmware, rebooting quite a few times, running some tweak tests (you can find them here in the test section of this site)...and it seemed to 'magically' repair itself! Still not sure what the problem really was. My VoIP provider was having issues around the same time, so it could have been that.

I notice now that my upload speeds are pretty consistently running around 100kbs less when I'm using the VoIP, so that tells me the router QoS function is working.

When all else fails, disconnect everything, plug back in this order: modem (let boot up), router (let boot up), VoIP box (let boot up), then plug in your ethernet connections and boot up your computers...its worth a try...

As of right now, my only issue with it is that the firewall breaks my VOIP service (Vonage). Here's a snippet from the firewall logs:
2005-09-16 11:26:43 [HOST Attack: UDP Flood] (UDP) WAN to LAN 69.59.248.155:12960->a.b.c.d  :10050 [Drop]
2005-09-16 11:26:43 [HOST Attack: UDP Flood] (UDP) LAN to WAN 192.168.2.3:10050->69.59.248  .155:12960 [Drop]
2005-09-16 11:26:44 [UDP Flood] (UDP) WAN to LAN 69.59.248.155:12960->a.b.c.d:10050 [Drop]
2005-09-16 11:26:44 [HOST Attack: UDP Flood] (UDP) WAN to LAN 69.59.248.155:12960->a.b.c.d  :10050 [Drop]
2005-09-16 11:26:44 [HOST Attack: UDP Flood] (UDP) LAN to WAN 192.168.2.3:10050->69.59.248  .155:12960 [Drop]
The 69.59.248.155 address is Vonage, the a.b.c.d is my public IP and 192.168.2.3 is the Cisco ATA-186's IP. Since the router is dropping so many packets, no wonder I can't have a conversation with anyone.

I've sent an email to Belkin tech support... we'll see if they respond (after the h*** I just went through with buy.com's customer support, my expectations are low!!!).

Anyone here have any thoughts?

The really annoying thing is that turning off the firewall doesn't turn off the "DoS" .. umm .. 'features'. :(

UPDATE: Turning off the firewall AND REBOOTING allows VOIP to work. When you turn off the firewall, it doesn't say you have to reboot and it doesn't reboot for you. But I rebooted the router manually through the web interface, and Vonage started working. The worse part of having the firewall off is having to put my work laptop in the DMZ to get the VPN working, since Belkin won't allow you to forward anything but TCP or UDP... I need to forward IP 50 for the VPN client.
