Disappointing Orbi Wi Fi Speed with Virgin Media M500

Question

Hi All,&nbsp;Had my Orbi RBK50 since Sunday and am using it with ISP provided Router, which I have put into Modem mode.&nbsp;&nbsp;My ISP is Virgin Media in the UK on their&nbsp;M500 package. Their&nbsp;Minimum Guaranteed Download Speed is&nbsp;258 Mbps (which I know is wired, but I have gotten 450 mbps over wifi before with the NetGear Orbi and the ISP own Router before I put it into modem mode).&nbsp;&nbsp;I have added some screen shots of some of the speed tests I have been getting, which are done about 25 mins apart.&nbsp;&nbsp;Is there anyway of performing some tests to see if the issue is with the NetGear Orbi or if it is with my ISP?&nbsp;

Personally I would focus on your ISP connection first to rule out issues there, and then focus on the Orbi. Try setting up a&nbsp;Broadband Quality Monitor (BQM) here:&nbsp;https://www.thinkbroadband.com/broadband/monitoring/quality as it can give great insight to the quality of your internet connection. As you are in Modem mode, it will be the Orbi that will respond to the ping, so make sure you enable [Respond to Ping on Internet Port] under Advanced / Setup / WAN Setup.&nbsp;If you have a computer connected via ethernet cable directly to the Orbi (No powerline adapters in between), then it would be useful running speed tests on it at the same time you notice reduced speed on your other devices. Obviously not exactly the same time though.&nbsp;PS: Virgin only offer the Hub 4 to customers outside the 1 Gb package when they have considerable over-utilisation in the area as it uses DOCSIS 3.1 instead of 3.0. Not that they will formally admit that. I suspect the issue lies here.

What Firmware version is currently loaded?What is the Mfr and model# of the Internet Service Providers modem/ONT the NG router is connected too?

Burakiosaurus · Answer

Firmware for the NetGear RBR50 is V2.5.2.4

The ISP's modem is apparently based off Arris’s Touchstone TG3492 Telephony Gateway router.

I've found these details online about it (I hope it helps)

"So far as we’ve been able to confirm the Hub 4 also features an Intel Puma 7 (CE2752) CPU, can handle 32×8 bonded channels on DOCSIS 3.0 and 2×2 OFDM and OFDMA on DOCSIS 3.1, supports 3×3 MIMO on 2.4GHz WiFi (802.11n) and 4×4 MIMO on 5GHz (802.11ac Wave 2 – 1.3Gbps), 512MB of NAND flash memory and 1GB of DDR3L random access memory. Apparently it has a total of 10 or 11 internal antennas (we’ve seen both figures stated)"

They go on to say:

"Judging by these specs the Gigabit Connect Box (Hub 4) is a very close match for Arris’s TG3442 router (except for the inclusion of a USB 3.0 port and a few other smaller differences – design etc.)"

Any other settings on the NetGear / ISP Modem I could look to change?

I have gotten speeds of 400 mbps + ovwe WiFi since installing the NG last weekend, but right now it's hovering around the 100 mbps mark.

You can try the speed diagnosis steps in the community FAQ:&nbsp;https://community.netgear.com/t5/Orbi-AX/Community-FAQ-My-Orbi-speeds-are-slow-inconsistent-and-don-t-my/m-p/1984305/highlight/true#M7944.&nbsp; These drill down where the speed loss is being introduced and offers some configuration recommendations.

You ISP modem already has a build in router and wifi,&nbsp;This would be a double NAT (two router) condition which isn't recommended. https://kb.netgear.com/30186/What-is-Double-NAThttps://kb.netgear.com/30187/How-to-fix-issues-with-Double-NATCouple of options,1. Configure the modem for transparent bridge or modem only mode. Then use the Orbi router in router mode. You'll need to contact the ISP for help and information in regards to the modem being bridged correctly.2. If you can't bridge the modem, disable ALL wifi radios on the modem, configure the modems DMZ/ExposedHost or IP Pass-Through for the IP address the Orbi router gets from the modem. Then you can use the Orbi router in Router mode.3. Or disable all wifi radios on the modem and connect the Orbi router to the modem, configure AP mode on the Orbi router. https://kb.netgear.com/31218/How-do-I-configure-my-Orbi-router-to-act-as-an-access-point and https://www.youtube.com/watch?v=H7LOcJ8GdDo&amp;app=desktop&nbsp;&nbsp;You might also update to v40:https://community.netgear.com/t5/Orbi/RBR50-RBS50-Firmware-Version-2-6-1-40/m-p/1997895/highlight/true#M105941Factory reset and setup from scratch after RBS and RBR have been updated...Burakiosaurus&nbsp;wrote:Firmware for the NetGear RBR50 is V2.5.2.4&nbsp;The ISP's modem is apparently based off Arris’s Touchstone TG3492 Telephony Gateway router.&nbsp;I've found these details online about it (I hope it helps)&nbsp;"So far as we’ve been able to confirm the Hub 4 also features an Intel Puma 7 (CE2752) CPU, can handle 32×8 bonded channels on DOCSIS 3.0 and 2×2 OFDM and OFDMA on DOCSIS 3.1, supports 3×3 MIMO on 2.4GHz WiFi (802.11n) and 4×4 MIMO on 5GHz (802.11ac Wave 2 – 1.3Gbps), 512MB of NAND flash memory and 1GB of DDR3L random access memory.
