Title: Slow download speed
Post by: GonKona on September 12, 2013, 01:44:47 PM
Just got the 4500, but now the download speed is really slow.  It tested at 9.5 d and 5.5 up wired and wireless.  Wired connection through the sbg 6580 is 33 d and 5 up. 

firmware: 1.15
hardware v: A1
cable internet thru Time Warner
wpa2
mix n and g
motorolla sgb 6580 bridged mode

I live in Ohio. 

enabled  uPnP and Multi Cast
QoS ,Game Fuel, wish, and wps Off
DNS Relay on
Wan port speed is auto
checked cable
moved router
time was already set

These changes had no affect on the speed.

Sure your Modem is in bridged mode? To tell if the modem is bridged or not, look at the routers web page, Status/Device Info/Wan Section, if there is a 192.168.0.# address in the WAN IP address field, then the modem is not bridged.

Set WAN port speed to 1000Mb.

It happens on both pc connected wired or wireless

Changed the ssid
have tried mixed g and n and both in single
running 2.4 because everything disappears on 5
changed the channel to 11
wpa personal wpa2/aes only have tried tpik and aes
two computers connected wi fi
one cordless phone 5.8ghz
6 other wifi routers in the area no overlap or shared channel
set port speed to 1000mb

I tried each setting on one at a time then with all at the same time with no change to the speed.
Time warner put the modem in bridged mode router ip starts with 65

Hmm...the only thing I can think of that impacts speedtest is Gamefuel and the UpLink speed. If disabled it should be getting full speed even when enabled you should get full speeds. Are you trying different speedtest.net servers? I notice some are busier than others or don't give good results.

Could try to enable GF and see if the automatic uplink detects anything. Manually set the connection to Cable.
Check cable between Modem and Router, swap out to be sure.

Did you get this modem from TW or buy your own?

The modem came from Time Warner.  Tried several different servers all the results were all close to the same, with no change in speed.  I manually set the connect to cable and turned GF on. Automatic uplink shows 6020 kbps.  Checked and changed cable which had no affect on the speed.
Title: Re: Slow download speed
Post by: motherfo on September 12, 2013, 07:47:56 PM
Automatic uplink is working properly if it is showing 6020 or something close to 5000.

Are you downloading via a wired machine?  If you are wireless how many mbps are you getting?

You can always try a fresh flash of the 1.15 firmware. I used to have to do that periodically on mine.

Post by: GonKona on September 12, 2013, 07:55:31 PM
The speed stays consistent at 9.5 d and 5.5 up on a wired or wireless connection.  It is 30 d and 5 up connected directly to the modem.

Reflash the firmware.  Backup your settings beforehand if you are worried about losing them.  But flash it and use the defaults and then run a test.
Title: Re: Slow download speed
Post by: GonKona on September 13, 2013, 05:48:57 AM
Flash firmware and ran test with defaults and my settings still no change in the speed.  Not sure if this matters, but the mac address that is printed on the router is different from the address that is in the status menu.  It is the last number set in the address. Printed on the router the last number is 79 in the settings it is 78.

There should be 3 MAC addresses, WAN, LAN and WiFi. LAN and WiFi should be the same I believe.

Did you factory reset, upload FW then factory reset once again then set up from scratch using IE or FF?

Where did you get this 4500 from?

I'm curious why your not getting speeds as others are. The only thing I can think of is that there could be an incompatibility between the ISP modem and the 4500. Any chance you have a neighbor, friend or family member near by with a different modem model that you could test the 4500 out on? Kind of need to verify the 4500 with a different ISP modem if possible before ruling out the 4500 could be bad.  :-\

You could attempt this and see if speeds are any different:
Turning a router into an AP. (http://forums.dlink.com/index.php?topic=40856.0)
Unbridge the ISP modem and see what the speeds are while connected to the 4500 in this mode...

Maybe someone can review your router settings with you using Link> teamviewer (http://www.teamviewer.com) if your interested. Its safe and secure.

Post by: GonKona on September 13, 2013, 09:08:53 AM
I flashed the FW tested then factory reset and tested again.  I got the router used for $30.  I can try it at a family members house, but not sure when I will be able to.  The LAN and WiFi mac addresses are the same in the status page but not the same on the router itself.

Post by: FurryNutz on September 13, 2013, 09:33:40 AM
Hmm...possible the router could have been messed with specially if the MAC isn't the same as whats on the sticker ON the router.

Give the AP mode a try if you can while you figure out when you can test the router at a different location if you can.

You can also try cloning your pc's mac address under internet | manual configure.  And see if that changes anything.  I've gotten a different IP address that way before.  I was usually the same as the one if my modem was plugged directly to my pc.

Switched back to the old linksys wrt 150n and got 28 ms ping 29 d and 5.5 up wireless.  Going to take the 4500 to a friend tomorrow who has the same isp but different modem.

I turned the 4500 into an AP but did not change the IP in the config. I used the linksys router to hook up the 4500. Connected to the 4500 wireless and got 18 d and 5.7 up.  

When the connection was wired the only network that showed up was the linksys, with the cable connected to the 4500 to the computer, is that how it should be?

Change the routers IP address to something like 192.168.0.50. Then LAN wire a PC to the back of the 4500 and test the speed. Still slower this way?

ISP modem>Linksys Router>DGL-4500 in AP mode<>Wired LAN PC. Speedtest.net on PC. Ensure any Linksys features are disabled like firewall or rules and such while testing.

Title: Re: Slow download speed
Post by: GonKona on September 16, 2013, 04:06:59 PM
I changed the IP and tested with the pc wired and was 28-31 d and 5.5 up.  So with the speeds where they should be in ap mode does that mean that there is an issue between the 4500 and the isp moden?
Title: Re: Slow download speed
Post by: FurryNutz on September 16, 2013, 04:42:26 PM
Seems like it...need to test with a different modem if possible...

That will be the next step.  I was going to give it to a friend to test but forgot it in the car.

I got the router back from my friend.  He has a motorola SB 6141 or SB 6121 he wasn't sure which, I'm waiting for him to check. Both of these are just modems with no routeing features.  He had no issue with the download speed getting 20-25 mb down on a 30mb connect.  He said his upload speed was lower than it should have been. The modem I have is the motorola SBG 6580 that can be used as a router but it is currently in bridged mode.

When he gets back to me with the model of his modem I'm going to call Time Warner and try to get straight to a level 3 tech.

Ok, keep us posted. Means that the 4500 is working and maybe some adjustments maybe needed once the ISP reviews your cable line signals. Keep us posted.  ;)
Title: Re: Slow download speed
Post by: GonKona on October 02, 2013, 02:35:04 PM
So Time Warner tech support said that the router needs to be configured by D-Link support to be compatible with the motorola.  Is there something that D-Link can configure over the phone?
Title: Re: Slow download speed
Post by: FurryNutz on October 03, 2013, 07:19:21 AM
There isn't any networking configuration to make it compatible. All D-Link routers are already compatible with the cable network connection between the router and any ISP modem. It's up tot he ISP or the Modem Mfr to ensure it's compatible and working with routers. D-Link ensures that the routers work up to the connection of ISP modems I presume and nothing beyond that. If the 4500 is working on your friends other 6 series modems and it's not working well on the one 6580, I presume the problem is with the modem.

Can you barrow one of your friends modems and install on your system? Ask to see if he can swap with you as a test? If not I would try a 6121 or 6141 or 6180. I all cept the 41 and each one of them works great with my 4500. I haven't had any experience with this 6580... :-\

That's what i figured.  I guess I'll call them back and tell them D-Link said it was their issue.  If that doesn't work I'll see if they will send me one of their other modems.  My friend just let me know he has a SB 5101.

Went to the Time Warner store they gave me an Arris DG860.  All of the modems they have are also routers.  I switched it to bridged and I'm still getting 9.5 down.  Tried the settings from the other posts and moved the  d-link to another location.  Not sure what to try now.
