Wifi Key Dell Laptop

[Tarja Rabito]

Itried everything I could to turn the WIFI back on my Dell Inspiron LAPTOP 1545 after I recently did modification on my symantec antivirus, but failed. So far, these are the steps I performed in trying to turn on the WIFI.

As you've mentioned that you did some modification on the Antivirus. You may try to perform System Restore and see if it works. Press and hold the Windows key and press 'R' key. This will open the run window -> Type 'rstrui' without the parenthesis, click on 'Ok' -> This will open the System Restore window. Follow the on-screen instructions to restore your computer to an earlier date. Please refer Here for more information.

Hi I'm having the same problem with my Inspiron. Can't connect to my wifi now. F2 has no effect, and I go into windows,R and it won't let me restore. Doing a diagnosis on the connection wants me to plug in phone cable to the modem. It seems to have lots all information to my wifi. Any help??

Open Control Panel - > view by category - > view network status and tasks (in network and Internet) - > change adapter settings - > here you'll see "wireless network connection" icon - > right click - > disable - > right click - > enable - > right click - >click on connect/disconnect - > then you'll see the popup of available network at right bottom screen, select the one which you need to connect. That's it.

What worked for my laptop was pressing the Fn once (don't hold) then pressing the F2 next. It helps if you press Window (hold) and X before doing this, so you can see the effect of this procedure to your wireless network.

Thanks. I tried pressing the Fn once and after that I pressed F2 once and it worked! My laptop didn't respond before when I held the button down as I pressed F2. It helps when you press windows + X to see the effect of what you do to the Wireless network feature.

My internet's been playing up for the past 2 weeks or so on my laptop. Speedtest is saying my download speed is about 90mbps, but browsing the internet has become extremely difficult - trying to load any webpage can take up to 20 seconds, and is normally preceded by a "this page cannot be found" error message on Chrome which mentions not being able to find the DNS server.

I've fully scanned by computer 4 times over the past 2 weeks (3 with Kaspersky and 1 with Malwarebytes), I've changed my DNS settings so that it uses Google's DNS, I've tried other browsers and I've tried downloading new drivers. Nothing's come up and the problem persists, and my Internet is fine on other devices. Any suggestions on what to do?

Apparently on some systems, Dell is installing a utility called SmartByte. Theoretically it's supposed to prioritize important traffic like Netflix and minimize bandwidth to background tasks like Windows Update, but there have been several threads here reporting slow Internet performance that was resolved by uninstalling SmartByte. Try that if you find it installed on your system. Otherwise, yes testing with wired Ethernet (assuming your system has that) would be useful, otherwise let us know what router you use and what WiFi card you have installed in that system. The latter can be determined under Device Manager > Network adapters.

I've used the Intel Driver and Support Assistant, which said that all of my drivers are up-to-date. Before this, I had just downloaded a new driver for the Qualcomm wireless card in the laptop, but this has not helped.

I checked add or remove programs and couldn't find SmartByte. I connected via ethernet and from the 5 minutes I've tested it, it seems to be working fine. It's a Virgin Media Superhub 2 and the wireless card is a Qualcomm QCA9377.

I got decent (albeit reduced) bandwidth on high speed wifi and by using ethernet cable - but on lower speed wifi and on VPN connections the speed dropped to almost zero - often resulting in a time out error.

We have the same issue on 2 x Dell Inspiron 5000 2in1's - Dell ended up sending a brand new replacement and now both don't work! We uninstalled the Smartbyte and it worked great for a day or two and now the problem is back and worse as ever. It's extremely frustrating as a service provider having to spend almost a full engineers time with troubleshooting to be sent an equally faulty product.

I've just successfully resolved this problem. The wifi speed was significant better with charging status. And this gave me a chance to access the Dell website through wifi. I updated the lastest wifi driver from Dell website. After installing and restarting my computer, the wifi speed--as it had to be--improved obviously.

I wish those buttheads would check compatibility a bit more thoroughly before they dump that stuff on everyone's computer. I've been reading everything I could find on the internet and working on configuration changes, etc. all freakin day.

2) go to device manager, find network adapters, expand it, then right click on your intel dual band wireless and go to properties. Click on advanced, find throughput booster then enable it on the window to its right. Next go to transmit power and make sure it is set to the highest. Then go to roaming aggressiveness and set it to lowest.

For the past 3 days I have been trying to figure out why my wifi will not stay on. I restarted my laptop, and wifi will work for a brief amount of time then cut off. I have done about every possible solution from watching HOURS of videos on every single imaginable solution there is from device manager>network adapters>update/disable/enable/unistall/reinstall. Done every possible update from dell and windows. From "run" , services.msc>WLAN autoconfig>clicking restart and stop then start. There is plenty more but I have really tried them all I feel. I have only recently found the internet stays on and works fined when i am plugged in and that lead me to looking for the power management tab in the device manager>network adapter>wireless, but only problem is I don't have that tab and don't know where to go from here, this is my last stop i really did not want to have to get on a forum and type all this out i thought i could find an easy video or instructions like i do when i have any tech related issue but this is the one i have become fully stumped on. PLEASE someone help me. I want my wifi to work fully when plugged in or not plugged in?

I did this by going to Control Panel>Network and Internet>Network Connections. Right-click on the adapter and open the properties and click Configure. In Advanced, there may be an option for Band and you can select 2.4ghz. I don't have this option so I changed my Wireless Mode to IEEE 802.11b/g (since the b and g only support 2.4ghz).

Thanks for the help, I have still not been able to fix the issue, with these steps either. I have tried everything multiple times and have yet to find a new one, it has been a week and still nothing, I completely give up. Hopefully Dell can fix it and if not or if its expensive I will simply get another laptop and stay far, FAR away from dell this is just ridiculous

That didn't seem to fix my issue either, unfortunately. Though I did have a very long period of time without a disconnect. I did send some diagnostic information to Windows in hopes that they will find something with the diagnostic data I recorded. Who knows if that will actually be helpful.

On another note, I tried seeing if Bluetooth may be a factor, which I read in a very buried, somewhat older forum post somewhere (I can't remember where). Unfortunately for me, this does not seem to be a fix for my laptop, but perhaps it's a good next step for you?

Your apology is accepted and I am willing to move on with any further advice if you have any. I would also like to note this isn't my thread, it was originally started by squashcorn and I just happened to have the same issue and was sharing troubleshooting steps I had been given as well.

I recently upgraded my Dell laptop to windows 11. Since this occurred the wifi now disconnects after my computer sleeps from being unused for too long and does not reconnect even if I click on it manually - I keep being told there is a wifi connection, but no internet, which is not true, because my phone is connected just fine. The only way to make it work again is to restart the computer.

I've read similar articles where people have had this issue with windows 10, so have attempted to do the whole "Windows key + R, devmgmt.msc, network adapters, properties, power management tab" jam, but like others I'm also discovering that there is no Power Management Tab to uncheck "Allow computer to turn of this device to save power"

I'm not sure if when I was using windows 10 the wifi was powering down and was reconnecting automatically upon reopening after sleep, either way what is going on now since I've installed windows 11 is just annoying, I just want to be able to open my computer and go like I could on windows 10... do I need to reinstall wifi device drivers or something? anyone else experiencing this? any help would be appreciated.

hmmm.... yeah, but this was never a problem before widows 11. Not sure if this is exactly the solution I'm after. My laptop always managed to get wifi going again after hibernation/sleep no problems on windows 10.

Similar issue here, had it in the shop twice for the same thing. It says "no connections available" when it was connected seconds ago and my phone/tablet and other laptop call all see multiple connections with more than enough signal strength to connect. My phone hotspot will run a video game and it won't see that connection even though they're a few feet apart. Tried exchanging the computer for different one in case it was the wifi antenna but again after a day of use I'm back to having to troubleshoot and "fix as administrator" wait for the shut down and then hope it "sees" any of the 5 connections available. One more trip to the "squad" and I'm switching to a different brand. I can only take brand loyalty so far Dell!
