WiFi Slow after 2-3 days until reboot?

For the tech saavy on this thread who don't want to shell out another $400 for network gear.

A weekly reboot does the trick.  I have a raspberry pi at home, and setup a script to execute on the crontab and it's worked like a charm for a month. This script will log an entry to the system log with the prefix "[orbi]" if you wanted to see any history.

Crontab Entry - I keep this script in /opt/scripts/orbi, you can store it where you like.

#Sunday

Bash script below, found this on github and slightly modified. 

#!/bin/sh
#Parameters
ROOT_DIR=/opt/scripts/orbi
USER_PASS="your password"
LOGGER_TAG="[orbi]"
logger -t $LOGGER_TAG "Rebooting Orbi...."

#Clear previous cookie
rm $ROOT_DIR/orbi.cookie 2>/dev/null
rm $ROOT_DIR/reboot.htm 2>/dev/null

#Authenticate, get cookie, and token
wget -O $ROOT_DIR/reboot.htm --user admin --password $USER_PASS --keep-session-cookies --save-cookies $ROOT_DIR/orbi.cookie "http://192.168.1.1/reboot.htm"

#Parse token
temp_token=$(grep "apply" $ROOT_DIR/reboot.htm | cut -d"=" -f4 | cut -d "\"" -f1)

echo "temp_token = $temp_token"

#Execute the reboot
wget -O $ROOT_DIR/result --user admin --password $USER_PASS --load-cookies $ROOT_DIR/orbi.cookie --post-data "submit_flag=reboot&yes=Yes" "http://192.168.1.1/apply.cgi?/reboot_waiting.htm timestamp=$temp_token"

#Cleanup
