Common questions
My Kahf Router doesn't show Rtex Tech BD as the importer. What should I do?
It may not be an authorised import, and it may not be covered by our warranty. Contact us with a photo of the label and where you bought it, and we will check it.
How do I claim warranty?
Contact support with your serial number and proof of purchase. We will arrange a diagnosis and, if needed, a repair or replacement under the warranty terms.
Some sites still open on my network. Is it working?
No filter catches everything, and new sites appear every day. Contact support and we'll check your setup and filter settings with you.
Do you help with setup?
Yes. Call or WhatsApp us and our team will walk you through it.
