Ubuntu

Dropped connection, Realtek and Broadcom

Asked by Ted Parks

The wireless connection drops on my HP Stream 11 running Xubuntu 16.04 unless I am very close to an access point.

I am currently using a USB wireless adapter with a Realtek RTL8188EUS chip. But I had what seems the identical issue with Ubuntu 16.04 using the onboard Broadcom BCM43142 card.

I am especially baffled by the similar problem when using two different cards and drivers.

iwconfig:
wlxec086b0c3f21 IEEE 802.11bgn ESSID:"ATT6YXb2IG" Nickname:"<WIFI@REALTEK>"
          Mode:Managed Frequency:2.452 GHz Access Point: DC:7F:A4:99:73:B6
          Bit Rate:65 Mb/s Sensitivity:0/0
          Retry:off RTS thr:off Fragment thr:off
          Encryption key:****-****-****-****-****-****-****-**** Security mode:open
          Power Management:off
          Link Quality=0/100 Signal level=2/100 Noise level=0/100
          Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
          Tx excessive retries:0 Invalid misc:0 Missed beacon:0

Is this not a driver problem? How can I fix the dropping, which occurs in numerous settings, such as Starbucks and my university office?
