New Laptop: WiFi problem

Posted on 2011-05-03

Just bought the new Dell Inspiron 14R with the new Intel Sandy Bridge processor. It comes with the Intel Centrino Wireless N 1030.

For some reason, it is super slow at my university campus, or just dead all together. It shows the signal is at full strength, but when I connect the internet is really slow. I tried running a ping, and it shows me that its dropping packets -- 25% packet loss.

I then tried it in Safe Mode with Networking with the same results, which makes me think its not some software causing this.

I thought it could possible be the campus network, so I looked around, and the entire class is browsing the web.

I called Dell, and asked them to replace my laptop. They shipped a replacement, and at some point it worked OK, but now its been a day or two and its slow once again.

I have no idea what's causing this to happen. Is it a bad WiFi card? Maybe because this laptop is equipped with WiDi? I don't know, any help is appreciated. Thanks.

    Probably just the university internet.

    try it at a friends house or your own house.

    check to see if your firewall is blocking things.

    Sounds like your wifi is trying to go too fast. You can drop back to g, or limit to a 20mhz channel, or choose 5 ghz or 2.4 ghz only.
    Another common cause of this is multiple access points on the same channel.

    If you have AV software with a firewall turned on, make sure the Windows built in firewall is disabled. Also make sure you only have one AV software on the machine.

    professionalcomputersolutions: It works fine at my house. This is only a problem at the university campus...BUT only with my laptop. Not only that, but I also tried a ping test on a friends laptop, and his wasn't dropping any packets at all.

    aarontomosky: There are a multiple access point, one every 50 feet or something. I will try your suggestions and see if they help.

    wantabe2: This laptop came with free McAffee which runs its own Firewall along with the Windows 7 Firewall. I'll try disabling the Windows firewall and we'll see what happens.
