Ahoy matey! Based on yer request fer the cheapest wifi router, I'd recommend either the Xiaomi Mi Wireless Router 4C fer R348.46 or the Huawei Wifi WS5200 White fer R699. The Xiaomi is the most affordable option in the results and will do the job nicely on a tight budget. The Huawei is a wee bit more but still very reasonable and could potentially have better range/performance than the Xiaomi. Both should suit yer needs fer basic wireless internet around the home or office without breakin' the piggy bank. Let me know if any other details would help in yer router search!
