Practical Scenario 2: DELL Inspiron 15 5570 WIFI VERY SLOW – Frustrating

I’ve been seeing this in quite a lot of threads on the internet, there is an issue with the wifi module (intel dual band wireless-AC 3165) that DELL is using in its new line of laptops. I have Comcast’s 250mbps internet connection at home. I have several other devices (phones, tablets, chromebook) that get at least 40-50mbps with wireless connection (checked using speedtest.net app) but the new DELL laptop 5570 that I bought in January 2018 from DELL’s website is only getting 1-2mbps download and 3-4mbps upload speed. Can someone explain whats going on and help troubleshoot this problem. I’ve reset the modem, checked it’s firmware and updated the DELL system with all new updates. Wifi module driver is also up to date. I’m using DLink DIR 850L router. I hope I provided enough info. Please help.

Dell Support

Other brand users can update the driver from their respective manufacturer website or can update the wireless driver from the device manager.

Solution 6: Distance Between the Router/Modem and Device is Far

The more is the distance, the weaker is the signal and the slower is the internet speed. The router should be closer to the devices. Place your router as high up as possible to extend the coverage. Wi-Fi router should be placed as close to the middle of your home as possible. This helps provide the best possible Wi-Fi signal throughout.

Solution 7: Avoid Signal Blockers

Don’t keep the router on the ground, do not keep it in a closet or cabinet because it will deteriorate the Wi-Fi signal.

Items like a cordless phone, microwave, baby monitor, concrete and metals will block the Wi-Fi signals so try avoiding these items near to the Wi-Fi router.

Solutions 6: Avoid Congestion

If you have too many devices connected to the same network it will result in slow internet speed, try to minimize the congestion and use as less device as possible to enjoy maximum speed. Sometimes you have Windows update running on different or same devices in the background and you might not be aware of it.

Solution 7: Restart/Power cycle Your Router/Modem from Time to Time

Sometimes we forget to restart the router/modem at our home for months and this results in slow Wi-Fi speed. Most of the time only restarting the router fixes the issue. Shut down your PC, unplug the power cable from the router/modem and wait for 30-60 seconds and then reconnect the power cable, wait till router is up and all the lights are up, now start the PC and see the difference.

Solution 8: Contact Your ISP (Internet Service Provider)

If none of this help then you can contact your ISP and they can help you to update latest router firmware and will let you know if they have any kind of issue at their end.

Wrap up
