Using D-Link DIR-655 As A Switch?

Oct 6, 2012

I want to use my dlink Dir-655 router as a switch or a wireless hotspot, the reason is that i have to use a modem and a router for my network provider P2602HWT is the model i have to use, is there any way i could do this, right now when i try to use the dlink router as a switch after 5minutes the network stops working until i shut down the dlink. Also the router i have to use only has 3 100mb ethernet ports, the Dlink one has 4 gigabit ports. Any way i could use my dlink as a wireless hotspot and a switch without conflicting with my other router?

Can't Connect Through Switch TP-Link TL-SG1005D?

Mar 14, 2012

I added a switch (TP-Link TL-SG1005D plugged into a D-Link DGL-4100 router)) so I could add a computer or two to my network. I have my Vonage modem plugged into the switch and it works fine, but when I try to plug a computer into it, nothing. I've been trying to use an XP machine that I rebuilt, and I keep getting the "limited or no connectivity" message.

I've tried all the fixes I could find for that, and still no joy. I even plugged it right to the modem with no luck so I tried plugging my Windows 7 machine into the switch and it couldn't find the network either, but it works fine plugged into the router. When I go into the router, it has an IP address assigned to the switch, but the phone modem does not show up, where it did when plugged directly into the router. Is this normal?

Am I missing something simple here as far as the switch goes? The XP machine won't find the DHCP server and has the 169.254.XXX.XXX IP address with a MAC address of FF-FF-FF-FF-FF-FF. I've tried Microsoft's hotfix and releasing and renewing the IP...nothing. I know that's separate problem than the switch.

D-Link DIR-825 :: IPv6 Not Working When Using It As Switch And AP?

May 10, 2010

I am using my DIR-825 as a switch and AP. I have turned off DHCP and plugged the internet into the lan-1 port. This works perfectly for IPv4, but I cannot get IPv6 to work. On the outside there is native IPv6 running radvd. How should I configure IPv6 on my DIR-825?

D-Link DIR-601 :: No Internet Connection Behind A Switch?

Mar 10, 2011

Here is my configuration. My new DIR-601 router is connected this way. Wan port to Isp modem, LanP1 to a Win7 Pc1, LanP2 to a Linksys router, DHCP diisable using the 4 LAN ports as a switch in wich 2 Pc are connected 1) Win Xp PC2 and 2) Ubuntu 10.04 PC3.

The problem is , I can not access internet  behind the telesyn switch, PC2 and PC3 have no access to Html servers on the Wan, except if I define PC2 or PC3 , only 1 allowed at a time, as DMZ. If I plug PC2 or PC3 directly in  DIR-601 port everything is ok.

Why DIR601 port connected to a switch does not work  the same way than conected to a PC. Any solution to give Internet access to PC behind a switch ?

NB: This work if I replace DIR601 with DIR620 router.

D-Link DAP-1522 :: Administration Web Of Switch Is Not Available

Jan 10, 2012

my config : one DAP-1522 as an AP + one DAP-1522 as a switch, 6 meters between them, signal strength about 70. Any others wifi networks around my house. both with FW140b03.bin dated 01/14/2011.Most of the time, both work correctly. But time to time, the wifi link is ko. In AP status, the switch is mentionned connected (uptime = 3 hours ...). The red led is blinking on the switch. The administration web of the switch is not available and the link is ko. Unplug and plug power units doesn't fix the problem. I need to reset DAPs.From Dlink experts, i would like to get more description about issues :

- in switch mode, which are the events modifying the red led state ? what does blinking / off led mean ?

- in AP mode, what does "uptime ...STA ...." mean ? frames are periodically received from STA ?

D-Link DES-1228P :: Need A New Switch Under Consideration

Oct 26, 2011

I currently have a D-Link DES-1228P and it is way too loud for my office.Would like a quiet 24 port Gigabit switch with Power over Ethernet, but if that's not possible, I'll take it without the PoE and plug the phones in with the transformers they came with.Something quiet, not to elaborate, that can be managed by a web gui, 24 port minimum, prefer to have gigabit on all ports, need priority for VoIP traffic, and under $1,000. I'd consider something higher end, but don't think I would need the features or know how to manage it.

D-Link DIR-655 :: Can't Access Webpages After Hooking Up Switch

May 2, 2013

Previous setup without problems B1 Firmware 2.00

Cable modem>Router>4 computers + 1 wireless printer.. But i needed more ports so i bought a trendnet gigabit switch with 8 ports.

Then I  Plugged port 4 on router to >switch port 1

When all the computers are turned on and using everything at once i cant access websites but my skype works so i figure its probably a dns issue and my dlink is overloaded? I didnt try to access any sites with the ip only fail on my part.

Once this happened i immediately unplugged everything and restarted the router. I only have my own computer hooked up the router and did a firmware upgrade to 2.10na and my internet works immediately after but when i hook up another comptuer to the network i cant access any pages but my skype works..

TP-Link 300Mbps Wireless :: Using TL-WR1043ND As A Switch?

Dec 24, 2012

Region : UnitedKingdom
Model : TL-WR1043ND
Hardware Version : v1
Firmware Version :
ISP :

My house has thick internal walls, so WiFi does not propagate easily. I am fortunate to have FTTP. Therefore I have the following setup: At one end of the house there is a Genexis HRG1000 Fibre Optic Modem / Router with WiFi and 4 ethernet ports. One of its ethernet ports links to a Devolo 200Mb homeplug and there is a matching homeplug at the other end of the house which is linked to a WR1043ND. We have tried two configurations each with various settings. If we link into the WAN port it creates a separate network which cannot be seen from the fibre modem end (since the 196.168.1.n addresses are non-routing) and although this works, we cannot stream / transfer files from the PC (connected to the fibre modem by ethernet) to the smart TV connected to the WR1043ND. The TV can "see" the internet and things like iPlayer work. Various other gadgets can connect either by ethernet or WiFi and get successful internet access. Alternatively If we link into one of the LAN ports, AND disable both the DNS service and the DHCP server in the WR1043ND it all appears as one network, but although it is disabled, all the gadgets and computers try to use the DNS in the WR1043ND rather than that in the fibre modem and consequently there is no internet connectivity. We have tried several combinations of fixed and dynamic IP addresses, rebooting the WR1043ND and the PC etc. but nothing seems to work. What does work is giving both WiFi routers the same SID and password so that moving from one part of the house to another with, say, a smart phone transfers what connectivity there is seamlessly.

D-Link DIR-655 :: WHS Disconnecting Via DGS-1008G 8-Port Switch?

Dec 21, 2011

I have been struggling with my WHS 2003 (Acer EasyStore 340) for about a month.  It stated prompting me with port forwarding errors (DIR 655 router) a while back signaling that I would not be able to access my WHS via the internet. I ignored the prompts for some time as  was not actually using the internet connectivity to my WHS.I then added a D-Link DGS-1008G 8-Port Gigabit Desktop Switch to the DIR 655 Router as I ran out of LAN ports when I added my HTPC to my devices.then my WHS started disconnecting from my home network.  I could not remote into it wirelessly (via latop) using Remote Connection in Windows 7 nor could I access is via the drives I had mapped to it via my HTPC (wired connection to same router).i only know there is an issue when the server disconnects. As it does not have a dedicated keyboard or monitor I can only see the desktop when I remote into it wirelessly from my laptop.  When it disconnects I can see the WHS icon in my tray go from Green to Black.  And when I try to remote in, I get errors saying the WHS cannot be found.i started to think that maybe it was my DIR 655 Router.  I did the following with no success:

- Changed LAN ports
- Changed network cables
- Upgraded the firmware to 1.35NA
- Reset to factory settings
- performed 30-30-30 reset 
- physically forwarded ports for WHS (80/40/4125)

Given that I cannot solve the connection problem with the above router fixes, am I to conclude that the issue is with my WHS?

D-Link DES-105 Fast Ethernet Switch - Signal Constantly Being Dropped

I have another Ethernet switch on the system as well but it is a Gigabit unmanaged switch from D-Link and has worked well with video streams. I've removed the DES 105 from the circuit and videos play fine. Should I dump to DES-105 for another Gigabit switch?

TP-Link Dual-Band Wireless :: Use WDR4300 As Switch Rather Than Router?

Dec 6, 2012

Region : UnitedStates
Model : TL-WDR4300
Hardware Version : Not Clear
Firmware Version :
ISP : Verizon DSL

My DSL connection comes into our house in the basement and the DSL modem came with a router included. I bought the WDR4300 for the higher speed wireless connections and the gigabit ports. I really don't need the "router" functionality. I would like to put the WDR4300 on the second floor to give (hopefully) the broadest wireless range. However, I would like all my PCs (including those wirelessly connected) to be on the same sub-net. Is there a way to configure the WDR4300 so it acts like a switch rather than a router?

D-Link DIR-615 :: Wired LAN - Switch Of Router Just Stops Moving Traffic

Mar 29, 2013

Every so ofter, the switch of the router just stops moving traffic between the LAN and to/from internet, though the WiFi keeps working and can still use internet.

I can still use the router's switch, and ping other computers on the local LAN, what happens is that the router stop routing wired traffic from/to internet, the rest of the issue is still the same, I opened reddit on my smartphone and there it was working via WiFi, but the would have none of it for the computers on wired LAN, not even accessing the router's page or telnet.

It is like some service or bridge between the switch LAN and the router itself dies... I'm still clueless.

The only "pattern" that I see is that my desktop is on line, because I can be not at home for 12+ HS and I can connect remotely to the server (rd p and trans droid) so I know it has internet access, but sometimes I think this happens when I turn on my desktop, like just now, this morning, but again, I feel is not every morning, trying to be more scientific about it I come here after every time it happens to record it, and also set the record straight about the issue description.

So, assuming it is not a hardware issue, because I did not had this problem in all 2011 and 2012, I do not overclock the router neither use other than default TX power level.

- How do I begin diagnosing this issue?
- If it is a known issue with this builds? I could no find it.

My goal is to be able to provide info for debugging the problem and possible finding a fix/workaround it. If it is indeed hardware failing, how do I even begin to diagnose it from that POV? The message is empty...

Even with the new build r21061 still happened two more times. Now the real problem to me, is that I cant even revert it to stock firmware, I tried even with:

- unplug router
- press and hold reset
- plug router
- keep pressing until power led blinks orange
- enter 192.168.0.1 (PC must have static IPA, i use 192.168.0.200)

Can't open 192.168.0.1 in FF nor chrome and does not even ping. [URL]. I just want to get it back to stock or do not hang up the switch-to-router(ing).

Cisco Wireless :: 1142 AP Will Not Join Controller Through D-Link POE Switch

Apr 1, 2012

I'm trying to use 1142 APs with a 2504 Wireless Controller through a D-Link 48PT GBIT XSTACK SWITCH (DLI-DGS-3120-48PC/SI).At any rate, the 1142 AP joins with the wireless controller ONLY when I attach it directly to the controller.  When connected directly to the controller the AP functions normally and all is well. When I attach it through the D-Link switch, the AP flashs green several times, indicating that it can't find the controller.  I suspect that there's some setting on the D-Link switch that's preventing the AP from seeing the controller.

D-Link DIR-615 :: Connect 2 Wireless Modem Routers + Switch In Home Network

1. Green Packet DX-230 WiMAX modem with router
2. D-Link DIR-615 ver G2 (from my ISP)
3. D-Link 8 port desktop switch

I previously used the DIR-615 with my high speed broadband connection. However I had to move to a new house and here I can only get WiMAX. I want to...Place the WiMAX modem upstairs to serve as modem and wireless access point Have the DIR-615 function as the main router and firewall (downstairs) Use the switch to connect all the rooms in my house FYI my WiMAX modem has no connection configurations. I just plug it in and it'll connect automatically to the WiMAX signal. It has 2 LAN ports but no WAN port. From my understanding of networking, I have to turn off DHCP on my WiMAX modem, put it in the same IP range as my DIR-615 (192.168.0.100-199), and disable UPNP and NATPMP. After this I'm stuck.How do I tell my DIR-615 to use the WiMAX modem as it's WAN connection?Should I reserve an IP for the modem in my DIR-615?

Cisco Switching/Routing :: SG500X-24 / Link Aggregation On Switch And Controller?

Nov 4, 2012

I have two workstations running 7 Pro, each has a quad port intel card (PCIe) which I have created teams for on both sides using link aggregation. On my switch, a Cisco SG500X-24, I set up two LAG's with 4-ports each and have both servers connected as necessary. I turned on Jumbo frames and disabled energy saving. The teams were set up without LACP turned on, however I tried it with LACP and I also ran into the same problem. Both workstations have a 26TB arrays running in RAID 6 (so plenty of read/write speed), however, with this setup, I can only get about 100MB/s (single port speed) and multiple data streams cause the speed to divide. Only single ports blink on the cards as well.
 
Questions 1 is probably a no-brainer, but it's my first time setting this up, but once this is working properly, would it allow a single file to transfer at ~400MB/s or would I need to start multiple datastreams to take advantage of link aggregation.
 
Question 2 is what do I need to change to make the link aggregation work?
 
I do have a little linksys router plugged into a non aggregated port to do DHCP but that wouldn't mess anything up, would it? Considering I can unplug it once everything is talking, all the transfer should take place at the switch level, correct?

Cisco WAN :: 3640 Router / Catalyst 2912 Switch - Ethernet Link?

All four will not get a link light and the interface(s) show no errors. If I plug the Router nic  into virtually any other switch or workstation it works flawlessly. I put a switch between the catalyst and the 3640 and it works without error.
 
Steps I have tried...
 
1. Configure interfaces on both Switch and Router to Auto Speed, Auto Duplex2. Configure interfaces on both Switch and Router to speed 100, Full Duplex3. Try Both Crossover and Straight-Through verified working cables.4. Tried a second 2912xl-en switch
 
Both 2912 switches are factory defaulted, other then the changes I made to the speed and duplex to try to get them connected.Both the router and switches have been doing other functions (seperatlly) within our network for years?So my question is...Why is the NICs in the router compatible with every other vendor other than CISCO?

Cisco Switches :: SG300 Correct Configuration For Redundant Link Between Two Switch

Mar 9, 2012

I have two switch SG300-10 that need to be interconnect togheter with a simple redundant "cable fail safe" configuration.My idea is use the two uplink copper port of the first switch, connected to the two uplink copper port of the second switch.

How to create a working setup configuration? The first setup that i need, is with only one VLAN1 for all ports,
 
The second setup is with the VLAN1 assigned to the ports 1-2-3-4 of all the two switch, (linked togheter by uplink ports)
and the VLAN2 assigned to the ports 5-6-7-8 always linked togheter with the same uplink ports.
 
Is possible use the two uplink port at the same time, as cable fail safe? or use a uplink port 1 for the first group and the second uplink port for second group?
 
I need to use this configuration for audio cobranet transport, and i need to test the correct configuration for the primary and secondary audio stream, if can work togheter on the same VLAN or i need to separate the two stream, from start to the end.

Cisco Switching/Routing :: 4900M - Establish Link Connection Between 10Gbase-T Server Nic And Switch

Jan 2, 2012

I have an issue with a Cisco 4900M switch with a WS-X4908-10G-RJ45 half card.  The link connection between a 10Gbase-T server nic and the switch does not establish, i believe it is an auto negotiation problem.  The link fluctuates constantly between connected and disconnected when set to auto negotiate.  When the 10G half card port groups are configured for 1G connections it does the same.  If i hard code the server nic to 1G the link remains up when the port group is at 1G.  If i hard code the server nic to 10G the link stay down, i don't think the port speed and duplex can be hard coded on the switch end.  I have tried updating the drivers on the server as well as diagnostic tests on the nic, which passed.  The 4900M IOS code is version 15.0.2-SG2.  If i plug a laptop into the 1G configured port the switch and the laptop negotiate at 1G.  Also, i believe, if the 10G server nic is plugged into another 1G only switch the link auto negotiates to 1G as normal.  The server nic is an INTEL Server Adapter AT 10G, which became end of life in 2009.  I believe the half card came out in 2010.

Cisco Switching/Routing :: 3750-X Stacking Switch By Switch

Nov 18, 2012

I have two 3750-X configured to be a stack and I am planning to re-rack these somewhere else.  What I would like to know is what are the effects of having the master switch itself lose power?  Does it immediately just make the member take over master (there should be no election since there are only 2 switches??) and there would be no loss of connectivity?

Cisco LAN :: 3560 Cannot Ping After Moving PC From Switch To Switch

Apr 15, 2013

I have a 2 cisco switches that are at different sites one is a Cisco CAT4500 and other 3560. The connection between the switches is a layer 2 fibre link. CAT4500 and 3560 both have VLAN interface ip addresses in order for me to connect to the switches.
 
I have PC A connected to CAT4500 and PC B connecting to 3560. All these devices are the same VLAN and in the same subnet. I do have trunk links all the way though allowing this vlan as we run vlans. From PC A, I can ping CAT4500, 3560 and even PC B. This tells me everything is fine regarding Layer 2 & 3.
 
As soon as I move PC B and connect it to the other switch CAT4500 or move the other PC vice versa (this happens in both directions). Both switches learn that the mac address has moved locations and updates its mac address table accordingly. So when I do a show mac address table and show arp, everything has learned and moved fine. However when I try to ping any other device from PC B I cannot. So the 3560 switch PC B was originally connected to, I can no longer ping, the switch cannot see the pc also. It is as if PC B has not learned anything from the switch and cannot respond or reply to any icmp. I have tried this with different end devices, same thing. I am now thinking it has something to do with the switch.
