Depends on the device, what device do you want to run at full duplex? I have almost all my devices at full duplex including my Ps3, computers Etc. Most if not all router support full duplex, also I would like to say that I am sorry I didn't post any sooner to help you Nicole Smith, but I refrain from posting and reading when the user requires me to read an abusively long post. If you enable full duplex on the device you are allowing the router to send and receive at the same time (excellent for VoIP), also in order to achieve a full duplex of 1Gbps (500Mbps up and 500Mbps down) you must have a standard cat 6 cable and the device/network card must also support a gigabit connection. You can also do a full duplex at lower speeds such as 100Mbps (50Mbps up and 50Mbps down) But since this is a gaming router you would want to use it at its full potential. Also let me point this out, I am not really sure what you are requesting, I didn’t bother to read the essays. Hope I am not coming on too strong and my apologies if I may have seemed rude. Have a great day Nicole Smith (your name sounds nice)


That is someone what correct, but it doesn't  matter the speed. if it supports full duplex then it does, but apparently the DGL 4500. only does HALF DUPLEX, read the instructions, and specs. so you can see for yourself. i just spoke with D-link, a while ago. and one of there tech's confirmed its HALF DUPLEX, i was about to ask him another question, and the called dropped, when i called again, got another tech, and he told me something else. he said its Full Duplex. so its crazy, the specs, and instruction manual, said Half Duplex. this is also what the first rep told me at   D-link. and then the second rep.tells me its full duplex.

The only reason, you select your ps3 to full duplex, its because. ps3 lets you just choose it manually. but its not really going at full duplex, since DGL-4500 only handles half duplex.  you can also set it to 100, or 1000 half duplex or full duplex, and it will work. ps3 NIC card, is not that smart, and so sensitive. just try to transfer a big file, like 10GB. from your desktop or laptop. to ps3. with the DGL 4500, and see how long it takes. when i tried this, with other routers. its was faster. this was the test , we just finished doing right now.

the problem DGL-4500 dose not give you an option , for half duplex or full duplex, because it
-- only does 1, witch is half duplex.

I would also like for you to understand that 1Gbps full duplex will only work in the network (LAN) Specially in the Dominican Republic, were the internet (WAN) is not up to 1Gbps.

i know this, please read, the post complete, so you can understand better. i just did some test, with some people.

Nicole Smith that is incorrect, if the router does not support full duplex than a connection cannot be established at 1Gbps full duplex. Instead you will get a message saying a network cord is unplugged. Try going on a router that does not support 1Gbps full duplex and then go onto your on board computer card and set it to 1Gbps full duplex and you will get the message. The complications that I don't know are if the router supports 1Gbps Full duplex than that means it’s really 2Gbps (1Gbps up and 1Gbps down) As for the 10Gb file size, you need to do it with a computer in which the hardware supports a write speed of 1Gbps. As for the Ps3; The test is invalid, The PlayStation 3 hard drive cannot even write at the speeds of 1Gbps, also most if not all network card will never reach a speeds of 1Gbps, just because it is possible does not mean the average consumer have the necessary hardware to perform at that speed/size. Have a great day Nicole Smith.

Also Nicole Smith, may you please use proper forum standards? You are quoting me wrong and it makes for a more challenging reading.

Umm, lookintomyeyes.. I understand what your trying to say, but im just making you a point, just because im a girl, does not mean i don't know or have the knowledge. I have my bachelor degree in computer science, Networking and Communications. 

what you are talking about, are just the Interfaces, of the Router only for transferring files (RECEIVE) (SEND). witch are

WAN : 1 x Ethernet 10Base-T/100Base-TX/1000Base-T - RJ-45,
LAN : 4 x Ethernet 10Base-T/100Base-TX/1000Base-T - RJ-45,
USB : 1 x

what im talking about, is the communications Mode (RECEIVE) (SEND), of the Router witch is HALF DUPLEX, and not FULL DUPLEX.

these are 2 different things


also one of my inconvenience right now is that when i called D-link Customer Service. When i speak with 1 tech, he tells me, yes DGL-4500 is only half duplex in Communications Mode, but full duplex in its interfaces.then when i was about to ask him another question, the calls drops. and i call again. and another tech. answers. and i ask him the same question, and he says, its full duplex. So this just confuses people.



 the only way to test, and know what im talking about, is if you have at least 3 routers, and 3 different modems. and testing them out, to see what i mean.  We have already conducted about 6 different test. on VOIP and gaming online.with different modems, routers, and router,modems 

Everyone has these issues, with the DGL-4500 router , the problem is, that no one really notice or get lag in online games, or doing VOIP.  you really don't notice anything if your only using the DGL-4500.  But when you have  5 different branded name routers, and 5 different branded name modems. and spend 5  to 6 hours in a day. testing it out like we did. then you'll notice the difference.

Some people, in other forums, have tested, with at least 1 different router, and they notice the difference. but its better to have more than 1. to make the test and compare. each test with each one.


also check on the NIC card on PS3 SLIM, its Better than the NIC card on PS3 Fat. we already tried this. and if you have a PS3 Slim and Fat. you can try it yourself.

Thank You, You have a great day as well.

Im still curious if you have set up the gamefuel rules or not. Funny, most of us on here who play XBL don't seem to see these issues you see while gaming. How ever again, some of us don't have 5-10 gaming consoles online either. Whats your ISP pipe like? UP and Down speeds your paying for?

Yes, I do agree that Duplex modes of this router could effect how VoIP works. I've worked in the communications field for a while now. VoIP needs FULL Duplex to communicate. This router may not support VoIP as I've said before, this router was mainly meant for people who game and for general internet usage. VoIP is a specialized application in which this router might not be best suited for that application. Working in networking and communications, I've never seen a home or end user type of router used for main stream VoIP, specially in small businesses and up. The most I've seen that works well on this router is MagicJack, as I have it on my system and on a 4500. I working on verifying to see what Duplex mode this router supports and will try and report it back here. If you are working with VoIP and need to have it for your communications, I would recommend researching to find a better suited router for that application.

[FurryNutz]

Some information about the 4500 that you should know:
"If the devices are only negotiating at half-duplex my first thought is check the cable. The DGL-4500 is not limited to half-duplex and it would appear that there may be a auto-negotiation issue between the 2 devices. However, if she is using wireless on any of the devices then we should expect half duplex as the 802.11 standard is half-duplex by design. Things like 802.11n (MIMO) have allowed to circumvent that by sending and receiving the data over different channels for example. You cannot specify the duplex mode on the router but may be able to on the end device to see if this helps."

Can the 2Wire DSL modem be set up for bridge mode and use it only as a modem connected to the 4500? If so, can you try this out? What are the results here?

Also set up the game fuel rules for port 53 and 3074 for your xboxes and let us know how it goes. .

And just for sake of connections, I would recommend using CAT 6 cabling between the modem and router and all other devices.
1. Shortest possible cable length between modem and 4500.
2. Ensure all cables are in good condition and fully support Full Duplex modes over the wired connections. Some cables that come with devices have been found to be poorly made and low budget.
3. Cat 6 cabling and patch cables are very inexpensive. I bought a 1000ft roll last year for less than $100. I did a quick patch cable upgrade between all my devices and the router for less than $30 bucks. For a business running a lot of devices and has high bandwidth usage, it makes sense to take the extra time and money and ensure your network is fully updated, stable and working well.

 Nicole Smith, I admire women like you. Never in our discussion did I ever think you did not have the knowledge or capability's, I know that you are a smart girl/women. But Nicole Smith, the router is indeed able to perform at full duplex, the problem you are being challenged with comes in because the Router is set to auto detect full or half duplex based on the Nic and the cables. May you mind telling me what firmware you are on?, you did say "im using Firmware Version : 1.15,  2008/10/29" but I need to know if it's 1.15N/A. If it is 1.15N/A may you upgrade your firmware to 1.23N/A? I would also like to help config you router for the next test, I may not be able to set it at full duplex but I will try to optimize it for your gaming session. Also Nicole Smith I want to point out that I am also from the island born and raised in Usa. Have a great day Nicol Smith.

I would advise that the router remain at FW v1.15 until her issue is better understood, troubleshot and possibly resolved. V1.15 is a very good and stable version. I ran it on my 2nd 4500 with out issues. I really feel the issues lie with the configuration of the devices and or cabling. Once troubleshooting and investigation has been satisfied to the point of resolution or no resolution, then it's possible that FW update could be done. My 2 cents

[LookIntoMyEyees]

Well FurryNutz there has been many improvement on the newer firmware versions, I personally believe that she has done enough. But everyones opinion is welcomed, I would like you to help her as you been doing and than if the problems persist I will come in and ask her once more to upgrade and I will help her out. I do believe I might get it to perform better but I don't know about the full duplex on the Xbox 360's. Only Ps3 and Pc's can be achieved by changing a few settings.

Understood man. There is still some trouble shooting that needs to be done, i.e. modem bridging, cabling and gamefule rule set up that needs to be addressed and we'd all like to know the results of this. Updating FW may or may not fix her issues.

As for the xbox, I presume they are Full Duplex as in-game voice needs to be supported. I don't have hard evidence of this though.   This also makes me think that the 4500 has to be full duplex as having to work with gaming data and voice communications, if you think about it, would have to.

 Yes, FurryNutz the router is full duplex, thats for sure. I have come to understand that it is full duplex 250Mbps (125Mbps up & 125Mbps down) This is based on the router splitting the 1Gb between 4 Lan ports.

Sorry, i got some family member's that came to visit me, from overseas. so i'v, e been busy with them.  so that's why i did not reply any sooner.

FurryNutzs , is correct 115. is more stable than any other. the 2 wire can be put into bridge mode. the only problem, is that here in this country, they only have PPPA or as many call it, Point To Point Over ATM.  So its not possible to bridge PPPOA, if it was PPPOE yes. but not PPPOA..  was i have said, in my other post, i have configured, the 4500, and opened up ports.

the 4500 is full duplex, only in transmitting mode. but only half duplex in communication mode.
.
Thank you Furry and Alleyes. for your help. i mean it from the bottom of my heart. its a shame, Dlink customer service, you have to wait, almost 30 to 40 mints, to get someone on the phone. and can't answer to simple questions.

when people just play on the 4500, they don't see lag or anything. the only way you can tell, is when you play in different modems, or routers like we tested.

all eyes, i know you didn't, but that's what it sounded like. thanks and no worry' no bad feelings .. lol



What i need to do, is get DSL-2320B modem. open up.. through its configuration.. ive been looking at some sheets..  is there a way, to make the Modem into a router. even if its only 1 port..?  what i mean by this .. is ..   is there a way. that i can manually input the DNS  address into the modem. so it does not auto detect it..? this would be helpful.  this will help me determine. if it has something to do with the modem. and not the router..






thanks


i'm going to try.. some other test. ill go to the business now. and test with some guys. hopefully ill have some other results.

[FurryNutz]

The DSL modem is just that a modem only. If you had the 2540 or the 2640, those have built in routers I believe.

Too bad about the PPPoA.
How do you have the 4500 configured for open ports?
