I am a novice user just looking for consistency. I have noticed since upgrading to 1.31NA my connection drops often. I checked with my Internet provider and they are not showing my modem dropping off. When it does it is for a few seconds and comes back quickly. It is most noticeable on my VoIP which is wired. It is constantly breaking up and has become unusable. My desktop is wired and drops out as well. This is noticeable while streaming Sirius.
Are there settings I need to adjust? Keep in my I am very inexperienced with this. Unless I can get help I will be forced to get a new router. That would be frustrating considering problems were brought on by a firmware upgrade. If I understand correctly, I cannot go back to an earlier firmware version?
WARNING TO THE DEAR READER: OK, long post here so I can include some background details for you. I'm hoping this helps point out there are some issues in this firmware and compatibility with speed negotiation.
I understand exactly what DaveH has mentioned here. The same thing happened to me with the upgrade. I was actually a couple revisions behind on my 655 router (1.20) when I noticed my logs indicated DLink had firmware upgrades. For now, I'm wired directly and have the wireless disabled. I was very concerned about making the jump to 1.31 when it said "not reversible" (How dumb on my part for moving forward. How REALLY dumb of Dlink for putting such a mess out there - debate this later).
Something kept me from being able to hit the Net yesterday, so I had to reboot everything (modem, router, voip, computer) and started combing the logs of my router when it came back. I found nothing indicating the trouble and attributed it to a lost modem carrier link from upstream. (We had strong winds the previous evening, so maybe something happened to the lines along the way.) I could see a message indicating there were firmware upgrades waiting from Dlink. I was finally able to get thru to the Net and DLed both 1.21 (dir655_firmware_121_no_securespot.bin) and 1.31 (dir655_firmware_131.bin).
I applied
1.21 first and no issues showed up, so I moved on. My
problem started immediately after the upgrade to 1.31. My browser (firefox) kept dropping back to a page telling me the router was testing the speed and that I should wait to avoid impacting the test. Well, there was nothing I could do to it anyway and was forced to wait. The login screen appeared for getting back into the router and I had a really hard time getting the correct letters/numbers on the new GUI addition before the "testing" page would come back up. Each time the testing began, I would actually see the router reboot/reset itself (all the lights on the front panel would blink off and come back like a reboot). I had my setting saved on my computer for the router, so I thought I needed to hit the "reset" button and get a clean start. It didn't make a difference. I finally had to disconnect the router from the modem to stop the testing so that I had a chance to get into the router interface.
I looked for all the spots I could find to disable automatic speed testing. I disabled the new security GUI feature first. I ended up turning off the traffic shaping and automatic upllink speed testing and set a LOW manual uplink speed. I'm using Road Runners Turbo package that is supposed to be 15M down/ 1-2 up, but I set the speed to really low (384Kbps). I searched for other things I could turn off and think I even tried turning off the QOS engine completely. This seemed to stop the problem, for now, and I could get back online. It was important to get connection as my only phone right now is VOIP. :-)
Finally got thru the extremely annoying front line RR support and got a 3rd leve guy to the phone. We verified that my cable modem was the one model they had in the field that did NOT support turbo speeds (nice!! - never told me this 6 months ago when I upgraded to turbo) and I should return it for an upgrade. Everything else tested fine along the line and they did not have any reported outages or issues for my area. Hmmm. Well, SOMETHING happened somewhere as I was dead Thursday. Moving on, I was able to use the Net and VOIP for the rest of the evening and switched the modem out today.
Intially I left the setting alone on the router and just tried to hit the Net. Connections to a few sites worked ok. Then I went back to using the traffic shaping and automatic uplink speed testing and I had my connections between the router and modem start acting up again. The router wasn't restarting this time but I could see my network icon in the tray indicating I lost network connectivty to the modem. Nothing would resolve in DNS for the websites (page not found) until I changed these settings and rebooted the router. I am running now with the QOS engine back on, traffic shaping allowed, but have manually set my uplink speed.
I know this was a long post, but I wanted to get this information out there so others can possibly explore the same thing. Better yet, I hope Dlink admits they still have issues out there and need to address immediately.
Good luck, gang.
