    I have the same problem with an Encore wireless router. Tried turning it off and on, banging it against the wall, move the antenna socket, even squeeze it as a piece of bread.

    After some time it goes back to normal.

Don't know if it makes a difference, but using a UK peice of hardware in Spain may be the problem. Or have you had it working before now? No saber si diferencia, pero usar un peice BRIT?NICO del hardware en Espa?a puede ser el problema. ¿O lo has tenido el trabajar antes de ahora?

Router dont work

Try resetting your router and then configure it again.
To reset the D-Link back to the default settings -
Press and hold the RESET button at the back of the router with the power ON until the LEDs flash at the time the release the RESET button. (firmware version was 3.00, and upgraded to 3.05) Connect a LAN cable from the D-Link to your laptop/computer's LAN port, open the browser on your laptop/computer and enter the D-Link's configuration URL..
http://192.168.0.1
The default login = admin
The default PW = blank (just press Enter) You can now change the default admin password.
You can now configure the wireless settings. (SSID, WPA or WPA2 encryption to protect your wireless network and Internet from unauthorized access). Now configure the wireless card in your computer/laptop with the router's wireless settings. To secure your wireless network from unauthorized access, please click on this link and follow my instructions :- http://www.fixya.com/support/r3559128-wireless_router_security

I have a DIR-600 router to connect my Cable modem and use wireless connection to connect to the internet. It was all working fine till my modem LAN port got damaged somehow.I have changed the modem and now...

Try following this order before you connect your computer to the router.
power off all your equipment (cable modem & router & your computer's wireless card)
first, power on the cable modem, give it some time to boot up and get an IP from the ISP, say 30 secs.
then, power on the router, again, give it some time to boot and obtain its internet IP from the cable modem
finally, enable wireless on you computer and connect to the router.

if this doesn't solve the problem try resetting the router to factory defaults by pressing the reset button at its back for about 10 seconds with the router powered on.

This your router's manual it may turn handy:

I have a Zhone ADSL2+ 4 Port Wireless Bridge/Router, model number 1518-A1-UK-0MA. it as working perfectly until one day when i turned it ON, only the ADSL LED is lit, no other LEDs are on, nor the power...

Please use the following steps:
1. Remove the router and connect it directly from the pc to the modem.
2. Power cycle: turn the modem off and then the computer for 30 seconds, then turn them both back on, modem first.
3. Check you internet connection to see if it working.
4. If it working, connect the router back up. If it not working contact your ISP for dsl support.
5. Once the router is connected, release/renew the ip address. Go to the dos command type ipconfig/release press enter. Then type ipconfig/renew. Check your ip address, you shouldn't get an ip address starting with 169. If you do, this mean you have a problem with the router getting an ip address.
6. Check you internet connection after the release/renew

To Configure the Router with Internet Access

Connect to one of the wireless router/access point's LAN Ethernet ports, turn off its DHCP server, and give the wireless router a static IP on your LAN:

  1. Connect a PC directly to a LAN port on the wireless router with an Ethernet cable.
  2. Power on the wireless router/access point.
  3. Reboot the PC.
  4. Log in to the wireless router though a browser. (Usually 192.168.1.1, with User Name = admin and Password = password, unless you changed them from the defaults).
  5. Go to the LAN IP menu and disable the wireless access point's DHCP server by unchecking Use router as DHCP server.
  6. Select LAN IP, and change the IP to 192.168.1.99.
  7. Click Apply to save the settings. You will lose the connection to the wireless router/access point , since its IP changed.
  8. Log in to the wireless router/access point with the URL: http://192.168.1.99
  9. Connect one of the wireless router's Local (LAN) ports to your existing network

I have a WRT54G router and want to daisy chain a Linksys BEFSR41 switch off it, but I seem to be doing it wrong...

Not sure if you just want to expand the amont of computer you can connect to it or the wireless range but I would setup the BEFSR41:
  • Disable DHCP
  • Set an address out of the DHCP scope of the WRT54G
  • Connect them LAN to LAN if not use xover to connect them

Need basic step-by-step instructions on how to install my router.

To Configure the Router with Internet Access
Connect to one of the wireless router/access point's LAN Ethernet ports, turn off its DHCP server, and give the wireless router a static IP on your LAN:
  1. Connect a PC directly to a LAN port on the wireless router with an Ethernet cable.
  2. Power on the wireless router/access point.
  3. Reboot the PC.
  4. Log in to the wireless router though a browser. (Usually 192.168.1.1, with User Name = admin and Password = password, unless you changed them from the defaults).
  5. Go to the LAN IP menu and disable the wireless access point’s DHCP server by unchecking Use router as DHCP server.
  6. Select LAN IP, and change the IP to 192.168.1.99.
  7. Click Apply to save the settings. You will lose the connection to the wireless router/access point , since its IP changed.
  8. Log in to the wireless router/access point with the URL: http://192.168.1.99
  9. Connect one of the wireless router's Local (LAN) ports to your existing network.
This completes the wireless router/access point configuration.
  • You can now log in to the wireless router/access point at its new address of http://192.168.1.99 and configure wireless features such as WEP and Access Control List
  • UPnP, DMZ, Port Forwarding, and Port Triggering are not used on the wireless router/access point, and it doesn't matter how they are configured.
  1. Configure the LAN IP address to be within the same subnet as your PCs.
    • Take care not to use an IP address already being used.
    • Limit the number of addresses in the DHCP range and assign an IP address outside of the range to the router you want to use as the Access Point.
  2. Disable DHCP on the wireless router/access point.
  3. Connect one of the LAN ports on the wireless router/access point to a LAN port on the Router.
  4. Configure the SSID and any security settings on the wireless PCs to match the wireless router/access point's SSID and security settings.
a. SSIDs must be the same on all wireless devices. (These are case-sensitive: netGEAR is not the same as NETGEAR.)
b. Tip: Make sure the wireless PCs can connect before configuring WEP, WPA-PSK, or other wireless encryption.

Hi,could some one walk me through setting up my Billion modem wirelessly to my Dell Desk top running XP home. I get confused with firewalls,LAN settings etc Ethernet cable is being used at the moment. Do...

I am not familliar with that brand, so I do not know if it is a cable/dsl modem, a router, or a combination of the 2. I will assume it is the cable or dsl modem since you said modem.

The thing we need to do first is give you a basic understanding of whats what, and how it works.

Imagine a 3 tier water fountain. Water flows from the top, to the center, to the bottom.

Your home network is the same way. Signal flows from the MODEM to the ROUTER to the COMPUTER CLIENTS in that order. Keep this in mind. Also, remember you never, NEVER setup a router from a wireless computer client. you ALWAYS use an ethernet connected client in port 1 2 3 or 4.

Quick education about Firewalls: They are programs and devices that are designed SPECIFICALLY to BLOCK TRAFFIC. Think of them like Toll Roads. YOU have to open each virtual port for inbound, outbound, or both. Since that is such a painstaking thing, most firewalls come with default port settings, blocking the most typically unused traffic ports and monitoring the common ones, such as port 80 (the internet port) port 110 (the sending mail POP port) and port 25 (the receiving mail SMTP port). That is why typically, people who can get online (but cant send or receive email) have to disable their firewall or antivirus (security) suite, because the program is closing the ports making them useless. IF you have a router, theres a 99.9% chance that YOU WILL NOT need a firewall. Routers are firewalls by nature.

Quick education about LAN (LAN means Local Area Network, meaning a router inside your house or inside your office or a series of switches and ports setup in your apartment, your "local area") settings: Most lans are DHCP, which means nothing to you, but, in lamens terms it means that you hook it up, turn it on, and it auto configures itself. In the olden days, you had to tell your computer its address, and tell the router its address and the address of each computer, and so forth. Thanks to dhcp, they can now negotiate a lease and assign that info automatically. SO, make sure DHCP is ENABLED. and make sure your lan settings are set to "Obtain ip address and dns server automatically".

Quick education about drivers. you DO need drivers for the wireless devices, you DO need drivers for the ethernet devices, but you DO NOT need drivers for the router, and YOU DO NOT need drivers for the modem. DO NOT HOOK THE MODEM TO THE COMPUTER THRU USB! USB is never to be used unless you do not have ethernet capability, it's like a spare tire. Remove any USB wires from the modem and put them away please! The ONLY wires you want in the modem are POWER and ETHERNET. (they dont make USB routers because USB is not a networking device, USB is a peripheral device)

You will be using Ethernet connection. An ethernet connection requires that you only have the ethernet drivers. So:
YES you need to make sure your ethernet drivers are installed and that your ethernet ports are enabled and working, and:
YES you need to make sure that your wireless card is enabled and functioning, and radio is switched to ON.

Now, remember the fountain? We are going to build it here. The trick is that we have to reset the DHCP list. (if we dont, then it wont work because DHCP will be stubborn and try to talk to the other items, not knowing they were removed). So, we will need to unplug power to the modem and router and shut down each pc client... after you print these directions of course.

While everything is off, hook the main computer into PORT 1 on the router. Make sure that PORTS 2 3 and 4 are empty. (fyi, you can use those for xbox, ps2/3 or wii, or any extra computers). Now, look for a port that says "LAN" or "ETHERNET" or UPLINK on the router. (it will be an ethernet port that doesnt have a number). hook that to the cable/dsl modem. You should now have the modem, hooked to the router, the router hooked to the main pc. Lets start the water flow.

plug power into the modem and wait 1 minute for DHCP synch with the company. (usually you see a sync light or a ready light).

once the modem is synched with the ISp, plug power to the router and wait 1 minute. (so the router can get the dhcp from the modem)

If your modem and router are combined in 1 device, then just wait for synch with isp.

Now start the main computer and try the internet. If you can get online, you have a good network connection. The rest will have to be done by the wireless router mfr, but it isnt hard. In fact, by default, you should be able to start your wireless and get online through it now, but you may want to consider wireless security, (WEP WPA) settings. Call the rtr mfr for those. (its not hard, just tedious and this post is long enough already).. lol. Quick note about wifi: its flaky. If you have a 2.4 ghz phone in your area you may drop connection (wireless only). try different wifi channels to resolve the issue, (call router mfr).
