Title: The DIR-655 died
Post by: rasteward on October 25, 2013, 05:23:37 AM
My DGL-4100 suddenly died after nearly 8 years of flawless service and I replaced it with a DIR-655 (Hardware Version: B1, Firmware Version: 2.10NA). Region USA. Wired connectivity to router. Factory reset was performed. No firmware updates applied (admin/tools says no update available although I'm aware 2.11 is on the website). The DIR-655 is connected to Comcast's business network SMC Networks modem and with static configuration setup with an offset dedicated gateway. Essentially the DIR-655 is configured the same as the DGL-4100 it replaced. Within a day of operation, the DIR-655 began to evidence this error message in the log. Although I suspected this as evidence in the problems of connecting to https sites, based upon your discussion in this thread, I think not. Although I turned all options on in logging, there is no correlated reflection of the hang-ups experienced in connecting to secure (https) sites. These hang-ups, lasting up to 30 minutes, eventually go away without intervention, only to randomly appear throughout the day. I reset the DIR-655 to factory defaults and within a day, the problem returned. On a second reset to factory default, the DIR-655 died (power light went to flashing amber/yellow and the DIR-655 could no longer be reset). Believing there was a defect in this particular DIR-655, I purchased another DIR-655 while waiting for the RMA process to bring back a usable router. Again, the new DIR-655 within a day began experiencing the https problem on all browsers (IE, Chrome, Firefox). I used your troubleshooting settings and rebooted the router, but within half a day the problem returned. I noticed that other owners (elsewhere) were experiencing this exact problem using 2.11NA so I have not updated the firmware. Any suggestions?

The problem I'm having is https connectivity. I believe I gave all the answers to the autoreply. Thanks for any assistance.

Please reply with some feedback to the question asked in my post so we can get a better idea of what is going on and provide you with better feed back. Especially ISP modem Model #. Please check out some of the suggestions as well and see if they help.

Internet Service Provider and Modem Configurations

    What ISP Service do you have? Cable or DSL? Comcast Business Network
    What ISP Modem Mfr. and model # do you have? SMC 8014
    What ISP Modem service link speeds UP and Down do you have? UP 5.85Mb/sec Down 30Mb/sec
    Check ISP MTU requirements, Cable is usually 1500, DSL is around 1492 down to 1472. Call the ISP and ask. Link>Checking MTU Values 1500
    For DSL/PPPoE connections on the router, ensure that "Always ON" option is enabled.

Already tried the troubleshooting suggestions you have given

Thanks!

From looking at the model of the ISP Modem, The 8014 series, I believe is a gateway or has a built in router.

Comcast controls access (username/password) to the modem. It's my understanding that it's a dual-IP Gateway/Bridge, with one IP allocated to the Gateway, and one to us (our static IP).

Here's the thing. There was a gaming gigabit router (DGL-4100) on this modem before the DIR-655 with no issues for quite a long time. The DIR-655 has no issues with http, other WAN traffic (including encrypted remote access), or on the LAN, even while the https is going "stopped then go" (last episode was 25 minutes ago for 10 minutes). No log entries. Nothing registering in the IE10 Network logging other than the timeouts after losing contact with the secure site. I've tried in IE 9/8 emulation modes, the defanged Chrome settings you recommended etc. It happened with both DIR-655s running 2.10NA.

Is the 655 getting a public IP address or a private IP address? Private being anything beginning with 192, 172 or 10 on WAN side on the 655?

Was a Factory Reset performed before and after any firmware updates then set up from scratch?

Could be anything between the ISP modem and the 655 router. I have not experienced this with my 655 using v2.10 nor v2.11 or any other version of FW, however my ISP modem is a stand alone modem with out any router built in. The ISP modem could be interfering possibly in some way.

Was a Factory Reset performed before and after any firmware updates then set up from scratch?No firmware updates have been applied, but based upon your site guidance, I did the factory reset to see if that would fix things even though this unit came in virgin.

I have screen snaps of every modified setup page on this unit if that's of any use? Before getting to this forum, I ran into someone else on another site who had this exact problem on a DIR-655 running 2.11NA, but no one there could help him either. Would going down to another firmware rev be advisable? e.g. 2.07NA

I would conclude that this could be an issue or something between the ISP modem an the router. The 655 handles any HTTPS traffic and data that it gets with out any processing. It's up to the ISP Service, Modem and Browsers being used to correctly handle and process the HTTPS traffic and data. There isn't any specific settings needed to be configured on the router nor are the any known HTTPS issues with the FW as HTTPS is a critical protocol of any router to pass certification and security measures.

Did this user come to the forums? Was his ISP set up similar? I ran my 655 on v2.11 and v2.10 for several weeks with a roommate that works from home using VPNs and logging into different secure sites, banking and other sites for HTTPS, never had any issues here.

Lets try this, Go to v2.11. Do a factory reset first, send the v2.11 FW .bin file. Factory reset  once again after it comes back to ready and don't re-load any saved config files and just set up basic WiFi settings and leave everything else alone.

Test and let us know what happens...

Are these HTTPS specific sites you visit all the time or various ones? Happens with all of them?

I have a DIR-655 running at my home office, also Rev B1 with no issues, but at 2.07NA, hence the previous suggestion. No, the other user was at another site. He was Comcast, but had a different modem.

Lets try this, Go to v2.11. Do a factory reset first, send the v2.11 FW .bin file. Factory reset  once again after it comes back to ready and don't re-load any saved config files and just set up basic WiFi settings and leave everything else alone.Can't do this without disrupting office operations and since the problem is random, I won't know if that worked for some extended period of time.

Test and let us know what happens...

Are these HTTPS specific sites you visit all the time or various ones? Happens with all of them? Happens with all of them. Everything https. Thanks for your help. I really appreciate it. My plan going forward is to switch away from the 655 if I can't resolve this in a timely manner.

If you have the same router at home, and its working there then that should tell you one thing. Is your ISP modem the same at home or different?

You have the ability to test this out at home since your work environment is critical. Update at home first. Test and check the results. If it's good there, you can just swap out the home router with work router after hours and test would be a good suggestion.

I really feel this is an issue with the ISP modem and the router. The ISP modem could be handling the traffic differently since you changed routers. The DGL has similar data standards however the HW is completely different and not the same. Also maybe the DGL was maybe experiencing some issues however was able to compensate for it thus hiding the real problem for false negatives.

Let us know if you can test at home first then do a swap after work.
