Hello,

For the past few months i have been having rather slow download speeds on my dgl 4500.  Modem to computer i get 15mbit down and 4-5mbit up. Modem to dgl 4500 over wired and wireless i get 3-5mbit down and 4-5mbit up.  Im on 1.23na FW and have no clue.  Any help would be appreciated

What is your ISP service? Cable or DSL? Have you made any changes to the 4500? Do you use static IP addresses or DHCP addresses?

[kaine13x7]

Cable. No changes. DHCP.

[FurryNutz]

What ISP cable modem do you have?

Have you tried a factory reset of the router from the Tools/System menu?

How about setting up a Static IP, set Firewall to EndPoint Independent for both TCP and UDP. Make sure DNS relay is enabled. Turn off any Advanced DNS services.

Hey Furry... long time since the last post.

I am actually having the same exact problem as kaine with download (upload is fine). I should have 30 down (as I have experienced in the past), but I am barely getting 16 wired and 12 wireless. I have the exact router setup described in the sticky for the Xbox... with static IPs for all devices on the network. Using firmware 1.22NA. FYI- wireless is in g only mode at 2.4 with auto channel scan.

My ISP is Optimum Online (Cablevision).

Here are just a few things to try to do to narrow down what the problem could be:

1. Save the Configuration. Do that first and foremost. Don't want to experiment and end up making it worst.

2. Bypass the router and go direct to set a control at that particular moment. Could be your testing direct at night, and router by day, and giving you a false negative. **Also* check what your DNS servers are direct to modem and write them down.

3. Reconnect the router and go hardwired using the same computer you tested wired on. If slower, continue on, if the same, no problem found.

4. Disable Gamefuel. Save settings, try the test again. If faster problem found, if slower, re-enable it and continue to next step.

5. Disable advanced DNS(If not enabled, skip this step). Save settings and run the test again. If no change re-enable and continue.

6. Disable DNS relay and manually fill in your DNS addresses. Save settings and test.

7. Make sure any AV is turned off. Alot of times when a new connection is tested, it can be given different security settings that effect testing. Norton/Mcafee are the two biggest culprits of this.

If you don't know how to do some/all of these tests, respond and I will break them down specifically. Good luck.

I have Cox HSI, yes i have tried a factory reset to no avail.  I have firewall set to endpoint independent for tcp and udp.  Disabled advanced dns and enabled dns relay with no luck.  Also setup a static up and not working ><

Did all this with no luck.  In logs i have noticed quite a bit of this...

Blocked incoming TCP connection request from 221.192.199.48:12200 to 72.222.213.76:27977

Blocked incoming TCP packet from 68.71.209.230:80 to 72.222.213.76:58977 as PSH:ACK received but there is no active connection

Blocked incoming TCP packet from 72.14.204.104:80 to 72.222.213.76:59020 as FIN:ACK received but there is no active connection

What is COX HSI? DSL or Cable?

[Hard Harry]

You tried all that today? To the letter, or you tried that here and there over the last week and maybe just skipping a step or two you think isn't the problem?

Because if the former, I only have one other idea, and thats turn everything off. Gamefuel, firewalls, NAT, put the PC in the DMZ, everything. Turn off logs, turn off anything and everything that could have any effect on throughput. If still a issue, I am out of ideas and suggest you go with another router. Sorry.

[kaine13x7]

I tried it all last night, and its cable not dsl.

[Hard Harry]

Yup, I am very familiar with Cox HSI. No conflict there. Don't have any other idea, sorry. If you tried a factory reset, all those steps, and disabling everything in the router, would have to either be firmware or hardware.

[kaine13x7]

Which firmware should i be using?  I have a config file if anyone wants to look at it...

[FurryNutz]

you could try v1.22 or v1.21 however not sure if that would work. Could be that you might have a bum unit. I can look at your config file when I get home this weekend.
