One more thing if anyone can do this when you upload your configs can you also include a packet capture of activity when your WAN connection starts to slow down or lock up.

Does this firmware increase the DHCP reservations? The one thing I hated when I went from a DGL4300 to the DGL4500 was the small reservation limit. I have around 50 devices on my network and with the DGL4300 I didn't have a problem with the number of reservations. But the DGL4500 for some reason has a paltry limit of only 24.

That's a lot of devices to connect to a single router.  If you are connecting that many, maybe you need to find a new business class device or something to handle that load.  These are home routers, not meant to connect more than 20 or 25 devices max.  What some of you people do, is going above and beyond.  If it fails, well...then that's on you.  That's more user error than anything.  Again, it's a home class device, not meant for THAT many devices.  With that many devices even, you could still cause the router to malfunction, from so many connections.  On average, each device MAY have at least 50 or more concurrent connections.

I will definitely say that there are MANY problems with this firmware.  Hence why a lot of people are having issues.  A lot of which you people thought I was crazy, when I experienced them and reported back. Go figure right?

And as stated earlier, you cannot downgrade firmware.  

Now, I will say that a lot of you have provided a LOT of good feedback.  One of the biggest problems I believe is to be the UPnP not forwarding correctly, regardless of the NAT filtering settings.  This is a problem.  One being, because it can flood the table, and cause your router to lock up as you have said. And two, it can cause connectivity issues as you have seen (such as locking you out of the GUI/requiring a hard reset) via WAN and LAN and even over the WLAN.

Cooling these routers is another big thing too.  If you can, bust out the stand that you have, and set the router upright.  The antennas should be like a T shape, while it's standing upright.  

My suggestion is to just be patient while waiting for a fix.

No problem. I can only hope that it and a record of my SysLogs can lead to a quick fix so my router will work as it did when I bought it and even improved like updated firmware should do.

One of the reasons that some of us have purchased this router is because it is a high-end residential device (as is the DIR-855 which is practically the DGL-4500's sucessor).  As such, it is to be expected that numerous devices will be connecting to the router more than your average home network. It is unreasonable to expect people with extensive home networks to spend thousands of dollars on business class equipment when they are not running a business. I might not have 50 devices, but I do have roughly 35 devices connected to the network. Does that mean I'm running a business and need business level equipment? No, because my existing equipment does the job just fine when it's working properly. Yes, I might want to consider using business class network equipment if I had the money to afford it and wanted business level performance. However, as homes become more digitally connected we will see more powerful home level devices to support them and more homes with devices that interface and connect to the home network.

DefaultPlayer, this is NOT a high end home networking device.  It is like ANY other one.  The only difference is that it's more geared towards people who game.  This is what separates that from business class devices.  Those ones are meant to handle the load of 30 or more concurrent network devices simultaneously running.

Again, it's not some top end gaming router.  It's like any other router for a simple home network.  It's been stated MANY times that it cannot support more than 20-25 devices, period.

I have around 50 devices on my network. I have zero problems. I never need to reboot, I have no problem hitting 850mbs to 900mbs throughput on my internal network through the DGL4500 and have no problem hitting 50mbs internet download speeds and 20 mbs upload speeds from my FIOS connection.
I'm running firmware 1.15 on my DGL4500. My DGL4300 router also had no problem with several dozen devices on my network, although I only had around 35 to 40 devcies when I had my DGL4300.

Interesting, if it is not some top end gaming router than what router is? Why would D-Link market it as such and put a premium price tag on it? I was under the impression that these reasons is why it isn't branded under the normal DIR product line.

Additionally, I fail to see anywhere where D-Link specifically states that the router is limited to 20-25 devices.

Jesus. My DGL-4500 is going crazy. I had the firmware 1.20 loaded with no problems for the past few days. Now all of a sudden, my connection has been dropping like crazy. I must have rebooted 15 times. This is so upsetting!!!!!!!!!!!!!!!!!!

Spend a grand or so on a Cisco device and configure QoS.

It's all blinged out with an LCD and everything. Great marketing.

Alright.. everyone that is having this issue, we would like to take a look at your configs as some of you requested. Please save your config with no password so we can load it on our routers for testing.

**Before backing up config temporarily disable any firewalls and AV's and backup config from a wired connection to prevent any errors.

Also if you please can, to keep things organized put your config in a folder or zip it up before uploading and also attach a text doc of some sort with a description of your settings at home. (e.g. internet type, bandwidth, and modem) Please label it with your username on the forums so we can keep track of it.

We're trying to fix this issue so the more detailed the better

Just uploaded mine.

Thanks for those of you that uploaded! Also can anyone get packet captures of the router slowing down or locking up? A packet capture should gives us more details than syslogs.. But if all you can get is syslog that's fine send those too. Would rather get packet captures.. Do what you can, if you can.

Thank you all.

Problem is it's very hard to catch it when it starts slowing down.  I got lucky once and caught it but usually by the time I get to it the router stops responding completely.  What's the best thing for capture.  I have used Ethereal in the past.  Is there something better out there now?

[DLP]

Ethereal's new name is Wireshark, by the way. The lead developer changed employers a couple of years ago and wasn't able to retain the name.

[arod]

yes use wireshark

[arod]

For those of you that uploaded your configs and docs:

deafultPlayer & phat78boy:Config loaded successfully however there is a password, please temporarily clear the password, save config then add password back

kenshinhimura: Attempted to load your config, but the unit locks up and freezes. What firmware version are you running and what hardware version? config maybe corrupt. restore unit to factory defaults and Try to re-flash firmware 1.20 again and Build a config from scratch then save config.

Puffnstuff: your config somewhat loaded but gave me a message saying RESTORE OUT OF VALID RANGE what firmware is your unit? Please try to reflash firmware 1.20 again.

**Users listed above please upload configs again after following suggestions

MPDamon: you're the only one that loaded successfully and had no password, we will look into your settings.

And again if anyone can also upload packet captures, or if you want to go an extra mile try a video of  your router starting to slow or lockup. The more info I can get from you guys the better leverage we have to push to get this fixed.

**Remember to backup config from a wired connection**

I am experiencing the router slow down as I type this and am capturing packets with Wireshark as recommended.

Edit: I have now uploaded the packet captures and re-uploaded my config file without a password. My appologies about the first config file password, I did not reboot router after removing it for it to be applied.
