'Can't find server' errors with ORBI 753
I’m having some Internet issues with a newly installed Orbi RBK753 system, and haven’t been able to figure out how to solve them. What happens is that I will quite often get a “Safari can’t connect t...
What Firmware version is currently loaded?
Does this happend with both wireless and wired devices?
Your modem is on the older side of modems. It only supports 100Mpbs on the WAN to LAN where the Orbi and newer gereration modems support 1000Mpbs on the WAN to LAN. So possible that the modem maybe a bottle neck and possible one cause of these errors your seeing.
Thanks for the suggestions. I'm not sure about the firmware version, but I know that the Orbi did a firmware check when I first installed it, so I think it's up to date. When I try installing it again I'll double check to make sure it's the current one.
The modem is an older one, but the ADSL service I have is 12 Mb maximum, so the modem shouldn't be the bottleneck, especially since things work fine with the (also old) Apple router and SecureFi Almond.
Good point about the wireless vs wired, and I can't remember for sure. I think (think!) I had issues on a wired Ethernet connection also, and since the Ethernet goes from the Mac Pro to the Orbi Router Ethernet port, that still implicates the Orbi. When I switch back to the Orbi systems for a final test I'll check both wired and wireless to see if the errors occur equally on both.
All in all, it's very puzzling. Almost like the Orbi is dropping the ball somewhere, but doing so inconsistently. I would really like to get this working since the mesh functionality is great; 100% coverage throughout all floors in the house as well as outside, and the computer to computer WiFi speeds are also much better than with my old system.
Thanks again for the suggestions.
I feel that there maybe an issue between the DSL modem and the RBR. You can try this, revert the modem back to router mode. Configure the RBR for AP mode and run this connfiguration to see if anything changes the behavior. Though the modem is older and worked with other products, it maybe possible that the Orbi could be putting too much stress on the modem and due to the connect being 100Mpbs instead of 1000Mpbs at the WAN port, modem maybe a bottle neck and having problems passing traffic to the RBR fast enough. I beleve you are one of a few or the only one to post having this kind of problem and using a older modem that I've seen.
Thanks for the recommendations. I reconnected the Orbi network and got a "server not found" error in Safari within 10 minutes, so the problem still exists. I checked the firmware, and it's at 3.2.16.6_1.4.4, which seems to be the latest.
I then switched the Netgear router over to router mode, rebooted everything, and set the Orbi to AP mode. Things seem to be working, with an Internet speed test showing 11.8 Mb download, 0.76 Mb upload, and 23 ms pings (slow, but normal for my connection). The Orbi home page is showing an internet not connected error, although the Internet is definitely connected. It bounces back and forth between 'Good' and 'Not connected' every few minutes, but as long as the Internet is in fact really on, that may just be a bug or a byproduct of being in AP mode, although it seems a bit strange.
I'll let things cook for a while and see if this fixes the "server not found" errors. If it does, I guess it's time for a new modem.
Thanks again for the help.
Ok. Ya if the RBR is showing intermittent error on connect, it's having a problem with the modem. I would try a new updated modem, with with out a built in router and support 1000Mpbs on the wan port.
