![]() Old installers from Windows updates and a bunch of MCX files. Then there is the TCP Global settings if they're in the default mode then that makes it worst.Īlso internal sub system file structure if the registry is corrupted or have data junk files or dump load of temps that don't need to be on the system. All Windows even version XP, 7, and the 8 suffer from this too.Īgain there a tweaks free can correct this issue. You can changed the TCP.sys setting from fallback of 10 for MSC (max session connections)Īlso the Internet Bandwidth you are paying for say you had 50 mbps down, but the laptop was only using 3 mbps down. Not a lot you can do for tweaking the WiFi NIC. I can't figure out why is uploading files to the laptop is so slow (while at the same time downloading from it is working fine).Īre you just doing file transfers or are you measuring from a Internet browser? I used to change some options in the wireless card properties (Advanced tab) and it started working at 3+MB/s again but as soon as you restart the laptop it's back to a crawl. I have updated to the latest wireless drivers a few days ago and it was working fine until the laptop got restarted. I'm pretty sure it's the laptop's fault because I have upgraded my router 4 months ago and I had the exact same situation. But again, when files are taken from the laptop is all well and good. The weird thing is that the speed when I take files from the laptop to desktop is solid around 3.5-4MB/s but when it's the opposite the speed is barely a crawl 1-5KB/s, overall the connection basically freezes up for like 5 seconds before any action when thing are getting moved to the laptop. The laptop is a Dell Inspiron N5010 (i3-350M, 4GB, DW1501 Wireless-N WLAN Half-Mini Card) and even though the card is n I was never able to get speeds higher than 3.5MB/s when I was uploading files to the laptop from my desktop PC (forgot to mention the laptop's signal & noise averages -20dBm and -90dBm). We have a small home network with 2 PCs (desktop and laptop) that are both connected to a router (Asus RT-N66U) through wireless and ethernet respectively and the router is connected to the internet modem through ethernet cable too. I have been having this problem and not sure when it started but it has been at least a year since I started noticing it. I cannot access the wireless networks from either os.(I hope you don't mind that I copied this post from my thread on LTT since I really want to get help on this) I also have a dual booted system with ubuntu 15.10 installed as the other os. I am using a dell latitude e6420 atg pc with dw 1501 wlan half mini card and Intel (r) 82579LM gigabit network connection. Have checked the services menu all the important services like WLAN auto configuration are set to automatic. Windows networking diagnostics tells me to turn on the wireless switch. Have tried resetting the bios to factory defaults. When i try to disable the wlan driver from network connections and enable it my pc freezes and restarts aftr some time. I have tried updating the drivers from the dell website same issue. Sometimes after restarting it automatically connects itself but after a while shows no Internet access and when I try to reconnect, it again goes back to wireless symbol with a red cross on the task bar. It is still not able to search for the available networks. So I tried restarting and then as if by magic I got the network drivers listed under the network adapters in device manager. I was also unable to update the driver downloaded from the Dell website due to the error of unsupported hardware because I could not switch on my wifi switch since the wlan driver was missing. After checking I found that the wlan driver was not there under the network adapter in device manager. After restarting my pc today I saw the Ethernet symbol in the task bar with the wireless symbol gone.
