3G/4G LTE PPP vs. Direct IP: A noticeable difference in speed
Posted: Fri May 10, 2024 4:36 pm
Hello fellow Billionaires. It was while testing my new Huawei E3372s modem on my 8900X R3 router that I noticed the pronounced difference in speed between running the modem on stick vs. HiLink firmware (PPP vs. Direct IP under the Type column in Status > WAN). Download speed is particularly affected, dropping from an average of 55-60 mbps to a mere 15-17 mbps in PPP mode. Upload speed is comparable for both connection methods at about 20-25 mbps. Interestingly, running the modem as a PPP dialup connection vs. cellular connection (via network card) in Windows does not seem to affect speed and both connection methods provide comparable download speeds in excess of 60 mbps during low congestion hours.
I ran my tests on the 8900X using the patched UK f/w 2.52.d14_0323 since this is the most up-to-date version which supports this modem. The results are identical on original firmware.
I would like to run the modem in stick (PPP) mode since this allows port forwarding, which is unfortunately not possible in Hilink (Direct IP) mode since this activates the modem's NAT. Does anybody know if it's possible to tweak the router's PPP client so it will provide a download speed closer to the modem's capacity? Many thanks in advance.
