I needed to add my input on this new FW release.... IT ROCKS!
Just bought my DGL-4500 last week (from a US vendor). Since I hooked it up and clicked the upgrade firmware button during the setup I've been miserable. It upgraded to only FW1.15 (I live outside the US so maybe this was the latest FW on the closest FW source). I think it had FW1.02 in there before I clicked the button.
Ever since then I have experienced all of the following problems:
- Some website cannot be displayed and NEVER timeout (loading icon forever) (eg. www.delta.com)
- Most websites load fine, but some images on some websites never load (loading icon forever)
- My Thunderbird email client cannot connect to ANY of my email hosts to download new email (three separate email providers). Thunderbird makes a connection but eventually times out downloading the email
- WireShark captures indicated timesouts; checksum errors on packets; missing previous segment warnings
I tried reset to default immediately before loading the FW and immediately afterwards. Nothing seemed to help. I disabled any feature I wasn't using, but the above pattern was always there. From two different wired PCs. My iPhone connected over WiFi was able to load the mobile versions of the delta.com site.
Upgraded to FW1.22NA since it appeared to be very stable (based on comments in another thread). Same issues.
Downgraded to FW1.20NA... same.
Each time I would restore defaults before loading the FW bin file, and then restore defaults immediately after the load rebooted. Nothing helped.... until I loaded FW1.23NA.
So far, everything is working EXACTLY as I would expect. The two sites that I COULD NOT load on my Firefox nor my IE8 browser... delta.com and partycity.com... Both loaded on my first try!
Needless to say, (so far) I am VERY happy with FW1.23NA. If anything changes... I will update this thread. Fingers crossed for now.
Now, why did I need to go through all that pain? The difference between FW1.22 and FW1.23 are not significant, but they were night & day for my router.
I see one step that I did differently on the last FW load... immediately after loading the FW and the router had rebooted... I pulled the power connection because I had to leave the house and didn't want to leave an unconfigured/unpassworded router connected to my network. But I don't believe a cold boot is required for a FW update, is it?
If anyone knows WHY my router was running so badly under all the previous FW versions I tried... please chime in.
I might try loading an earlier version just to see if I can re-create the issue, but then again... why tempt fate?
