We were getting 30s-5m drops in connectivity at intervals between 5m-10h, conditions that were hard to reproduce. I began using Ping Plotter to help diagnose the issue. We continued to have the problem, however, I could always see a connection to the router (gateway).

I called Comcast and the technical support person insisted that "it is your router" and that "I am looking at the history on your modem and you have never lost connectivity, except when it has rebooted."

At the time we had the a A2 rev of the EBR-2310 wired router which was about a year old. I had my wife go to Best Buy and get a brand new EBR-2310 which is a rev B.

I configured the router the same as the old one, however, now when I crank up the ping frequency on the Ping Plotter sfotware to ping once a second, I loose connectivity a LOT more.

The log shows dropped packets:
[INFO] Sun Sep 07 10:31:24 2008 Dropped packet from 192.168.0.161 to 209.85.171.103 (IP protocol 1) as unable to create new session

This seems to be because the router cannot establish more "sessions"? (connections?)

It seems to me that the router is establishing a session for each ICMP ping.

The previous rev A2 of the EBR did not drop like this when I pinged frequently.

Is the hardware defective? Is there a setting I can change to get the rev B to work like the rev A2?

Hardware Version: B1   Firmware Version: 2.01

seems that i have the EXACT same problem as you. i emailed D-link a few minutes ago and ill give you there reply as well. very annoying issue, i understand

active sessions log:

Same problem.. my connection just dies or crawls so slow that I get connection errors every 5 or 6 minutes..

[Prime]

Having the EXACT same problem. Medium sized network w/ 22 computers. Win2K3 DHCP Server redirecting traffic to this router. As traffic increases dropped packets skyrocket.

Getting them as IP Protocol 6, 1, & 17. Makes the internet almost unusable. Disabling the DNS forwarding and UPnP helped, but its still stupid. Contemplating returning it.

Try crash resetting the router and reflashing the latest firmware on it

Also do not try to restore your settings from a saved config file, rather build your router configuration from scratch once again

[tallguy_az]

Did anyone ever find a solution to this or try crash resetting the router?

I have the exact same problem on network with 10 computers and it's driving me crazy.

Thanks!

How do you have 10 Computers going out through this router?

What firmware version are you running?

Is this in a home or business environment?

[tallguy_az]

The internet comes into the router and then from the router into a switch.  The switch has the 10 computers connected to it.

The firmware is version 2.01

It is a small business environment.

[tallguy_az]

I tried resetting the router, still have the same problem.  I'd love to hear from anyone else who might have ideas. 

[mach77]

Has anyone solved this problem?  My problem is very similar.  My connection will be fine for a few days, then all of a sudden I can't connect anywhere, ping my gateway, etc.  At this point I can still log into the router web control panel.  I can release the public IP, but when I try to renew it just hangs.  I have to unplug everything (my dlink cable modem & router) and plug them back in before it will work again. 

It also seems to have problems if you try and open a ton of connections at once (ie, open a bunch of different webpages).  Any solutions would be great or else I need a new router.

I bought a new Linksys router.  Haven't had the problem since.

[sailingboa]

It appears to be faulty firmware on the router.

The router becoming inaccessible periodically appears to be related to increased traffic through the router.

Does anybody know if D-link plans to fix the problem with a firmware upgrade?

Thanks.

[mhorva]

i have the exact same problem, as does everyone else who has bought this...

I wish I could get a refund; i always assumed it was tmc.

Why haven't they fixed this?  DLINK-- speak up already!

[BlackLightning]

I am having the same problem, While downloading or surfing the web I get connection issues droping and such, And when I play world of warcraft I have huge lag spikes disconects and Really high latency issues.  I am running the store baught version firmwear 2.01 right out of the box.

and aparently the website only has up to 1.05 and the better 1.05bb for other versions.

[johnj]

I am having the same problem. Intermittently drops connection to the internet/loses all packets.

EBR-2310 Hardware Version: B1 Firmware Version: 2.01

Still able to connect to default gateway (the Dlink route). Then I go to the Dlink admin web page and release and renew connection to internet all becomes well again. This is a pain, I NEVER ever had to do this with my previous router and now this happens on a regular basis with the Dlink.

Does D-Link support read this page? Someone from support offered up the standard boiler-plate in another thread, "reset your firmware". However given the number of people having this problem both here and on a quick Google search then this high number of diverse configurations would point to a firm-ware problem not a problem specifically to do with one person's hardware or router config. Not to mention the firmware for this router that is still on sale hasn't been updated since 2007.

When will D-Link be fixing this problem???
