I use DIR-655 in DHCP mode, without making reservation for any connected devide.

Well, time to time I have a terrible problem: I open a web page, and Firefox give error message, and donŽt load page. I push "try again" one, two or more times and page load. I always blame my ISP for that, and never tested this really hard isolating router... today I made some test: I fixed an IP in my wired network card and after that it seems problem doesnŽt appear any more... could really be a router DHCP fault? If yes, why this happens with wireless devices too?

Anybody else have this problem?

fgl30,

What is the frequency of your problem?

I only have one PC set-up with wired connection DHCP (not reserved). I primarily use Firefox (2.0.0.12) on it (winXP pro SP2, TimeWarner) and I haven't seen that problem.

[fgl30]

well, is a really strange problem... frequency is difficult to determine... some times per week... and it happens with wireless device too...

Hi Fgl30,

    I've not heard of the specific problem your describing, can you nail down some details for us? When you said, you have seen it on wireless too, what OS were you running on that PC? Please give DIR-655 hardware and Firmware currently running. I am really tyring to see if it is OS & Firmware specific/combination there of.

    I would request you to change the Lease time on the DHCP offers, then, comment back if problem is only occurring  with that loss of IP (due to DHCP Lease expiration) and then your sporadically not getting and Offer/IP back. This is not a wide spread epidemic with the DIR-655; just specific to your network at this time. Also, if you have upgraded your firmware and had not noticed this problem before, I would have you clear the router of any previous configuration (Reset to Factory Defaults) see if the problem still exists. If you have the time to do so, please let us know the outcome?

How is your network setup?  workgroup or domain, almost sounds like the dns server is not being located immediately

[fgl30]

workgroup....

[TaVARUS]

The next time this problem occurs, see what you can PING. Let us known what your able to Ping? If your able to PING IP Address on the Internet, but not FDQN (ie. google.com or yahoo.com); then it's a DNS resolution problem! If so, and your not using "Web filter" feature, then you can Disable DNS Relay (SETUP tab>> NETWORK SETTING page >> Enable DNS Relay option).

[fgl30]

Thx. IŽll try and let you know.

[Lycan]

What virus software / Firewalls are you running on that machine?

[fgl30]

@TaVARUS: not worked   In fact, if I disable DNS relay I canŽt connect to internet

@Lycan: I use AVG Free edition + winxp firewall

[Lycan]

Hmm, does the issue presist if the AVG is uninstalled?
Please give that a shot.

[fgl30]

unfortunatly, with or without AVG the problem persist.... I think this problem is with my ISP... 

[Lycan]

Well I don't think it's a bug in the firmware, however your unit may have gone south on you. Seems unlikely, but I'm failling to come up with another possible solution.
What is the make and model of the modem and who is the ISP?

[Sammydad1]

Hi,

I had a problem kinda like this a while back.  I ended up replacing my cable modem.  Problem went away.

@Lycan: my modem is a Motorola SURFboard and my ISP is aŽsmall local CATV...

@Sammydad1: thx. IŽll try that.
