Todd - Just to follow-up on my slow wireless on my Dell Inspiron 15 3521, I have been on the laptop for a couple hours this morning and the speeds did seem improved, but not all that satisfying. I had found an older thread with some suggested wireless card settings by I assume a Dell representative, SAHARSH K? The thread that he responded to was an issue of the wireless disconnecting. Although my issue was for just slow response speeds on wireless, I decided to make the changes he suggested to see if it might help my case! It did work and I am pleased with the wireless speed I am now getting. WIFI problem with Inspiron 15 3521 by Saty on 03/16/13. Again, SAHARSH K offered his recommended settings to this thread on 10/19/13. Anyone having slow wireless speeds on their Inspiron 15 laptop might benefit from making these changes to the network card settings. I have replied to that thread at the end letting all know what exceptions I found when making my changes! [URL] Thanks again Todd! Rick
New to the Dell Community Forum. Saw 3 other posts, but no solutions. My problem is not with WIFI disconnecting, but merely being slow as molasses. It's like watching paint dry! In desperation, I hooked up via an Ethernet cable to my Netgear router and wow, I got the speed that I would expect out of a computer. I realize speed will probably be faster on the Ethernet, but wireless speed should still be somewhere close! The other day I tried to reinstall a software program and the company finally asked me to call back when my computer could communicate faster. Now, I could probably make that call as long as the Ethernet cable is hooked up! I should not have to do that! If anyone out there has had the problem with slow wireless connection and has found a solution, please let me know. I would appreciate any feedback you may have!  Thanks - Rick
