Wireless Adapter Craps out

clerik007 · Post by **clerik007** » Mon Nov 05, 2018 7:18 pm

Running Linux Mint 18.3 on a Toshiba Satellite C55. After a short while of running fine, the Internet adapter fails and cuts me off wirelessly. Is there some script I can use to keep it on, or to turn it back on once it craps out?

I also have a Toshiba Satellite C55T-C5300 and the wifi is only 30% and Google/Netflix stutters often.
I attached a TP-Link TL-W722N v1.1 USB wifi adapter with 100% signal and same thing.
The Toshiba has a Broadcom BCM943142Y Dual-Band Wireless-N B/G/N 802.11N 2x2 WiFi and Bluetooth 4.0 NGFF M.2 E-Card Network Adapter.
I replaced the original card with an identical one, same thing.
So, I just ordered an Intel 7260NGW Dual-Band 2.4/5GHz A/B/G/N/AC Wireless-AC 7260 802.11AC 867MBps 2x2 Wi-Fi and Bluetooth 4.0 NGFF M.2 E-Card Network Adapter, and we'll see how that one works.
I detest Broadcom wifi adapters, and I always replace them with Intel adapters, if possible.

Make sure Power Saving Mode is turned OFF for your wifi adapter.
Good luck.

I just received/installed Intel 7260NGW Dual-Band 2.4/5GHz A/B/G/N/AC Wireless-AC 802.11AC 867MBps 2x2 Wi-Fi and Bluetooth 4.0 NGFF M.2 E-Card , and it works fine...75% connection.
The Broadcom card was only 30% and sluggish.

IS there a specific driver that I need to find and install? I am still having difficulty with the wireless dropping. I ran the script to turn off the energy saver. Is there something else, besides physically installing a new adapter? I am at a loss.

Try the rtlwifi_new driver from Larry Finger:

Have the exact same wireless nic that you do - here is how I solved my connection issues

Code: Select all

cd Desktop
git clone -b extended https://github.com/lwfinger/rtlwifi_new.git
sudo dkms add ./rtlwifi_new
sudo dkms install rtlwifi-new/0.6
sudo cp -r rtlwifi_new/firmware/rtlwifi/ /lib/firmware/rtlwifi
echo "options rtl8188ee ant_sel=2" | sudo tee /etc/modprobe.d/rtl8188ee.conf

viewtopic.php?f=53&t=280501

clerik007 · Post by **clerik007** » Mon Nov 26, 2018 11:21 pm

I've ran the script now to see if it works. I'll reboot and see how it goes. Thanks.

Post by **JeremyB** » Tue Nov 27, 2018 6:09 pm

You can skip the last command echo "options rtl8188ee ant_sel=2" | sudo tee /etc/modprobe.d/rtl8188ee.conf as it likely does nothing. You can check modinfo -p rtl8188ee | grep ant_sel to see if that parameter actually exists for the rtl8188ee module. The ant_sel parameter is used with the rtl8723be and rtl8723de when in HP laptops as HP decided to only use one antenna wire on a wifi card made for 2 antennas

clerik007 · Post by **clerik007** » Fri Dec 14, 2018 9:46 pm

Nothing seems to be working. Wifi works for a while then still craps out. I've tried all the scripts. i don't know what else to do. I think, perhaps, the wifi adapter is going out. The only solution is to buy and install another one. But this is an old laptop, I don't know if it will be worth it. What do you think?

Wireless is much more susceptible to interference, especially for high bandwidth application and those that use many connections (torrent clients). You can check for other nearby network signals that are causing a problem with INSSIDER, a free wireless signal analyzer.

Insure that you are using a channel that does not have other strong network signals (choosing from channels 1,6, and 11 the non-overlapping channels). Also, insure that you are using N only with WPA2 security and AES encryption. If there are no other wireless network signals detected you can try channel bonding (using a 40MHz wide channel instead of 20MHz).
Its a hardware and network problem.

All of this sounds interesting. I don't know how to change the channels on my router, it is a rental from my ISP. I guess I'd have to fiddle with it a little. As for the rest, I'll figure it out. I just know that I can run for hours with my wi-fi, now, then like last night, it just crapped out again.

Just a comment, Torrent clients don't work worth a damn with Satellite internet, actually much slower than a straight single connection download.

No way to change the channels on my router, it is what it is. Wifi still craps out, have to use the ethernet cable. Any suggestions?

My laptop's internal WiFi adapter card is a piece of useless junk

I just received this little repeater/LAN to Modem/ WiFi trick piece of gear.

https://www.amazon.com/gp/product/B07JB ... 2__o00_s00

it is the Cat's Meow...

My original intent is to use it with my Verizon Mini Cell extender via the Internet at hotels or other places where Verizon does not have coverage.... like when I was camping in Colorado, and the RV park had WiFi....

Hook the laptop via the Cat5 port to the Dodo extender/repeater and set it up Manually for the password to the Internet signal. The included Manual is terrific!!!

Then you can use it as the laptop's internet access point ( which I am doing right now ),
or plug in my Verizon Mini Cell repeater.... voila!!! I have service to Verizon's network.

But, what I discovered by using it today, is that it has not once, dropped out...
Whereas my laptop's WiFi connection continually drops off, even though I have Power Control turned OFF.

This thing is cheap at $18.99
..... you might think about getting one?
