Question about Belkin (F5D7230-4) Router (587009)
Power supply puts out 13 volts (says 9 on the case) and router heats up, baud or bandwidth slows to a crawl and router becomes useless. Can't even download email after a while. This is replacement for another which did the same thing. Both are Model #F5D7230-4. First router took a couple of months to "shell out" and replacement only took two days. "Tech Support" cannot seem to understand the problem. Input to power supply is constant 120 volts and surge protected.
Add repeater device with your router to increase single strength and boot internet speed.

Might be worth trying a different AC adapter. If you aren't returning it, don't hesitate to cut the cord on the adapter and attach its plug to a different one (get the polarity right!). There will be a voltage regulator in the router and if it has to cut 13V down to 9V, a lot of heat will be generated. Check the power or current rating on the replacement adapter and make sure it is good for at least as much as the original. I once had charge of a bunch of switches with AC adapters. They got hot and failed somewhat similarly to your router. The company replaced all the AC adapters with a different type and that solved it.

Return it and buy a better brand? It is normal for a router to get pretty warm - difficult to say what is too warm. You could try aiming a fan at it and see if performance improves - if so, that is the problem. Any way to improve ventilation? I suspect the 13 volt measurement you made is with no load - not connected to the router. It is normal for the no-load voltage of a power supply to be considerably higher than the working voltage. Perhaps you could rig some clipleads or open the router case to measure the voltage when it is connected and see if it is significantly higher than the 9V rating - which would be a problem causing overheating.
