Question about Dynex 5 Port 10/100 Ethernet Switch (DX-ESW5)

1 Answer

Lost connection between switch and hub - LED flashes every 5 secs

Upgraded my internet connection and it comes in on a wireless router. I have a CAT5 cable going to an 8 port switch and then distributed around my home. Two cables have 5 port hubs on the end; one works fine, the other doesn't. The one that doesn't has a laptop, XBox 360 and a wireless gateway. The incoming cable from the switch is connected to port 1 on the hub and the green LED flashes once every 4 or 5 seconds - it is picked up as being a network with no internet access by the laptop, which is too far from the wireless router to maintain a good steady internet connection. I'm assuming the intermittent flash means that it doesn't have a good connection, but it was fine before I upgraded the router (although before it did go into the router rather than a switch). I've tried connecting only the laptop, and eliminating the hub; connecting only the hub and laptop, but the results are the same each time. Any suggestions?

    What kind of router do you have? You flashed the router correct and ever since then you lost communication to the Dynex Switch?

You say you have the same problem when you connect the cable directly from router to laptop, so it apparently is not a hub problem. That leaves the router and the cable. You're fortunate in having a working system on the other port. Why not try swapping pieces to see which is the failed piece? For example, what if you swap the ports for the cables? If it's a router problem, then the "bad" cable should work when in the other port. What if you swap cables? That would reveal a bad cable. Finally, swapping computers would show a computer configuration problem, such as the connection not being set to automatic.

Is it possible to have 2 pieces routers to expand the distribution of internet connection instead of using router to hub? what type of cabling should i used to do it? please help thanks


I guess you have a single incoming internet connection and wish it to be shared.

You only require one DSL / Cable router. To share this connectivity you will need Ethernet / Cat5 or wireless.

An ethernet switch or hub will enable you to extend connectivity.

All cable should be CAT5e or CAT6.
Suggest you consider the slightly more expensive switches that have auto-uplink. The negates the need of crossover cables.

Your better bet is a wireless access point. It plugs into your router and can be configured to be transparent to the network so that any IP address you get for your wireless device comes from the original router (better for networking).

At the blinkingly fast speeds of your Wireless internet, "N" is a waste. Get the "G". Here's a link to the product I would use...it runs about $50. http://www.tplink.com/products/product_des.asp?id=116

Will not connect to the internet wired or wireless


Unplug your power from the modem first and after that unplug your power to your router, disconnect all your cat5 cables and wait for at least 20 secs. After 20 secs or so go ahead and plug your power back to your modem and wait until all the flashing green lights are solid and that the link light starts blinking. After that plug in your Routers power (You can also reboot your PC while this is going on) . Wait until all blinking lights becomes steady then re-connect your cat5 from the modem to your routers uplink and last the cat5 cable from the router to your PC. If you'd rather not test the direct connection then go ahead and switch your wireless on.

Your wireless connection properties on your PC under "Internet Protocol TCP/IP" should be set to "Obtain IP address automatically" and that "Obtain DNS server address automatically" should also be set. Your routers should, if not already, be set to automatic DHCP. Make sure that on your Device Manager > Network Adapters that your wireless network adapter is not disabled and that it has the correct driver (yellow exclamation on it indicates it needs correct driver). You should disable your integrated ethernet LAN card if you have enabled your wireless Network Adapter to avoid conflict.

On your Wireless Network Connection properties under "Wireless Network" tab go to "Preferred networks" and highlight your wireless network name (SSID) . After highlighting click on the "Advanced" button and select "Access Point (infrastructure only) networks only"

My network says that it can't find the internal wireless adapter


You may have to reboot your PC and try to connect again.
If you have "Viewed all available networks" and tried to connect to your Wireless network but cannot what kind of error message are you getting ?

To quickly find out if you have Internet Connectivity coming in at all from your Internet Service Provider turn off your wireless switch on your laptop and try to connect a cat5 directly from your PC ( connect cat5 cable to what looks like a slightly larger telephone jack on the side or back of your laptop) to the back of your router and see if you browse the internet. You may have to reset your router (unplug and plug)

Linksys wireless G CD will not install


Router setup
If you are using the cd that comes with the router, that is the problem. You do not have to use the cd. Go to the control panel and un-install the program that the cd installed.
then:
Connect the Cat5 cable from the modem to the WAN port on the router. Then connect a Cat5 cable from any port on the router to your PC's network port.


Shutdown your PC. Unplug the power from the router and the cable modem.
Wait 30 sec. then plug in the power to the cable modem, wait 30 sec. then plug the power to the router. Wait till you have "Internet" light then restart your PC. The PC should pick up an IP address and you should be able to get on-line. This is if you have a cable service provider. If you have DSL, the router needs to be configured with PPOe.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe

Modem wont load the internet while router is plugged in


It is hard to tell from here with the amount of detail supplied but here goes...
There are a number of things that could cause this:
1) Modem does not realize that the router is plugged in and has not given it an IP Address. Unplug the power to the modem and the router. Wait 60 secs and plug in the modem, wait another 60 secs and turn on the router, 60 seconds after this boot up your computer.
2) Some ISPs record the MAC addresses of the device connected, if this is the case you need to dig ot the router manual (page 53), go into the management console and have the router clone the MAC address.
3) Miswired. It should be ISP cable to modem, cat5 from modem to the WAN port on the router and then a cat5 cable from any of the ports labeled 1,2,3,4 to the computer. In your setup do NOT use the uplink.
4) Misconfigured router. Reset the router back to factory default by inserting a paperclip into the tiny reset switch located in the front panel.
5) Defective router or cable.

Pc connection problems


Sounds like you are setup to use Internet Connection Sharing. don't do this. Have each computer connect to the internet via the router. If the router is wireless connect all computers wirelessly to the router that are wireless capable and any computers that are not wireless capable, connect them to the router via a cat5 cable to the cat5 ports on the router. This will solve your problem. BPCS

My wireless router wont work


Run a cat5 cable from the laptop to a cat5 port on the router, open internet explorer in the address window type http://192.168.1.1 or what ever the IP address of the router once you have accessed the router create your PPPOE internet connection, enter your Internet Service Provider's username and password. Once you have done this, disconnect the cat5 cable and connect wirelessly to the router from the laptop. If all this fails press and hold the reset button on the back of the router for 10-15 seconds this will reset the router to factory defaults. connect to the wireless router and create the PPPOE connection.
