We have a home network. Currently, we have two computers connected to a wireless D-link router, a Dell Dimension, E521, running XP and a Gateway 556GE running XP. We also have a Dell wireless laptop. All of these computers can connect to our DSL internet just fine through the D-link WBR 1310, version B. I purchased a third desktop, a Dell Inspiron 530 running Vista. All of the computers can access the internet just fine, except the new Dell Inspiron 530. It will not access the internet no matter what I do. I bypassed the router and connected the new Dell straight into the modem and I could get on the internet great. But by doing this all my other computers could not access the internet. This tells me that my router may have to be set differently for my new Dell. What should those settings be and how do I do this. Thanks for your help.

Re: cannot connect to the internet
Open internet explorer, go to tools, internet options, then the connections tab and make sure ' never dial a connection' is ticked, assuming you had a dial up connection before using the router on this pc or if you briefly used it.

i agree with all the above.. it's definately clear as mud how the network is designed and or funtioning. The machines connected to the wireless d-link router.. are they via cat5 inthe wired ports or wireless ? is the server the machine thats connecting to the switch and wiress router and modem? i'd say reset all switches modems routers and machines.. shut them all down.. then fire the cable modem, then the wireless router then the desktop switch then the server, the workstations and the one lonely wireless.. run "ipconfig /all" on all machines and if they aren't all sharing common ips and access, provide the results here for further investigation.
Pay attention to part about 802.11n compatibility? Perhaps try changing the IEEE standard on the router to 802.11g in the set up pages, as it may be set at 802.11n, which your older wireless card will not see.
As to the acquiring ip address message, try using a static ip address, here's a good guide:-
contact Comcast and have them reset your IP address. also have them ping your modem after they reset IP. Also, see Linksys website for LELA (easylink advisor) to add devices to network. Uses a good bit of memory so don't allow to run automatically at start up.
The only difference in using a wireless hub is that it will go between your router and your computer. The advantage is you can take your computer anywhere within range and connect using your computers wireless card (if you have one).
You won't need any more equipment or memory and most wireless hubs come with instructions. If they didn't give them to you, just Google the manufacturer and model of the hub and you should be able to find them easily.
After you've set up the wireless hub (which you can still connect to via your ethernet cable). your computer should notify you of wireless networks available. You have a utility to set this up within the control panel.
Let me know if this helps
its sure an IP conflict is there and i hope you don't have a router - a modem is there so that when you connect to the internet, computers will get ip address from your service provider and not from your device which is not having that function because of no router. Kindly check in your network properties that you have specified any manual IP address delete it and keep the option obtain Ip address automatically. Before all this you have to go to the my computer right click and select properties then hardware ->devicemanager ->networkadapters - under that you uninstall all the adapters and restart your pc
The first thing u need to do connect ur router to the computer with a wired connect access the router page (firmware) ip address which need to enter to open the same on internet explorer is 192.168.0.1 enter the user id & password of router (default user id & password is admin or password)
step 1 go to wireless change the channel to 6 (this the best channel)
Step 2 go to add/remove in control panel remove the dell wireless utility
step 3 go to device manager in control panel go to network adapter right click on wireless network adapter & select uninstall or remove
step 4 Now click action on top of device manager & click on scan for hardware changes it will reinstall the driver
Step 5 now go to network & sharing center go manage network connection right click on wireless network connection & select the connect it will show the list of wireless network now connect to ur network enter ur security key once ur connected save the network & ur issue is resolved
