Wireless & Wired Internet Issue

**tec71** · 07-28-2009, 09:53 PM

I have two issues. Any number of computers can detect my wireless access point, but they can't connect to the web through it. It's basically dead. But I've got good Internet behind the access point through the wire. It's a terribly old Belkin 802.11b access point and I figure it probably just died. I defaulted it back to the factor default settings and restarted and rebouted everything but no luck. Before I throw it out, anyone have any last minute suggestions.

My second issue is that my new laptop and my work laptop both will not find the internet when I hook them up through the ethernet directly into the cable modem, but my old laptop still does. I can't figure out why. Any thoughts or ideas are appreciated.
Thanks

login info correct for your DSL service on your router? settings right on that router for your DSL service?

Check the phone line?

it's mediacom cable. everything is correct along those lines. but I'm going to go double check one more time.

all wireless doesn't work? but wired connections do work?

**tec71** · 07-28-2009, 10:06 PM

all wireless doesn't work.

wired works from my 5 year old lap top but not from my brand new lap top (or my relatively new work lap top; first time I've tried it through the wire)

the new does work with wired?

and all machines can't get through wireless?

sorry to be nit picky, just trying to get the whole picture.

MAC address filter on the router? is that enabled?...

Or maybe the router isn't masking the MAC of your wired old laptop... in fact I bet that is it. there should be a setting to mask the real MAC address with the wired network card MAC address of your old PC. then all MAC addresses will get through

Sorry if these questions have obvious answers but I'll throw them out anyway.

Are you sure that your new laptop and work laptop network cards are backwards compatible to wireless "B" and not just the newer "G" and/or "N"" compatible?

Did you ever have anything other than your wireless AP plugged into through ethernet to your cable modem? It could be that your have a fixed IP address and you need your Access Point working properly to hand out DHCP addresses. If this were the case then your old laptop would connect if it had a fixed address in the TCP/IP properties. Also, if you have a fixed IP from your cable company, then your cable modem most likely would only have one ethernet output port instead of four.

mediacom only lets registered MAC addresses through... I am sure that is the issue

i only have one output on the cable modem so I'm just unplugging it from one laptop and plugging it into the others. I had been running threm all through the four port router on the back of the wireless point but that didn'tt work either.

it's possible it's a backward compatibility issue with the b access point, but i've had issues with my b wireless card on my old laptop too.

i will try this stuff and let you know how it turns out.
thanks for the help.

Honestly, hook up the router. login to the router with your old laptop and have the router mask your wired MAC address.

99% sure this will work.

You're going to have to power cycle the cable modem before you can change the computers plugged into it. It will only recognize the first MAC address it sees.
