OSX provides ipfw to define custom firewall rules. Using this tool you can create a pipe with limited bandwidth. When you assign the throttled pipe to a specific port, this port's bandwidth is limited. Quick How-To. Create a pipe '1' limited to 500KBytes/s via. Sudo ipfw pipe 1 config bw 500KByte/s. Furthermore, how many users can be served by a single access point using 802.11. Stack Exchange Network Stack Exchange network consists of 174 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. Whenever i turn my 2015 MBPr on it gobbles up the network bandwitht. Other devices (macbooks, xboxes.) start to lag and have performance issues) Once it i turn off my MB the network goes back to normal. This is with my MB running at idle at the desktop and after multi OS wipes even jumping between OSX El Captian and macOS Sierra. EDIT: WIFI dongle - using that manages to get the stupid thing to behave perfectly! Internal wifi chip, not so much. I have an appointment with Apple Sunday but was wondering if anyone had any thoughts. Edit 2: At the apple store waiting, I didn't bring down the network like i did at starbucks (much more robust network, would expect that being an Apple Store) but I can see running a few speed tests that the demonbook Pro is making its self known. Thanks • • • • •. Good lord you weren't kidding. I recommended LS so you'd be notified of every app / process that wants network access. You could then deny them one by one and figure out what's raping your bandwidth. Background syncing (iCloud or otherwise) is almost certainly the culprit in my non-professional opinion. Bonus shot in the dark troubleshooting step: deny all programs network access (LS) and see if MBPr's mere connection to your home network has ANY impact on the performance of other devices. External video card for mac best buy. Using the internal Wifi connector, can you provide the RSSI, Noise, Tx Rate and Phy Mode? You can obtain this by holding down the option key while selecting the Wifi icon in the menu bar. Provided that you haven't moved your MBPr to a new location, then the chances are that you might have a problem with the internal Wifi as you indicated. Causes could be a bad Wifi module, damaged cable, or bad antenna. If the module is only receiving a weak signal it might get stuck at a low modulation level and this would potentially pull down everything else on your network to a slower speed. Genius Bar is probably your best bet, however normal (or even Apple's extended) diagnostics might not pick this up. You might need to compare the RSSI, Noise, Tx Rate and Phy Mode on your MBPr to a couple of other Macs in the Apple store. This is fascinating. I reckon it might be ddosing the network. If there's literally no programs running then i reckon it's either a software fault in the kernel/drivers, or a hardware fault or something like malware. So you have an external Wifi adapter (like a USB one?). It would be interesting to try that to eliminate the possibility of a funky driver or hardware fault. I would also recommend trying on a different Wifi network - uni, work or apple. Because it would be embarrassing to take it to the genius bar only for it not to be repeatable and there might be some magic with your Wifi network. I would also try a Ethernet connection straight to the router to see whether it is Wifi contributing to the problems. There is such a thing as the 'hidden terminal' problem in Wifi that can cause congestion, so if your Wifi devices are spread at opposite ends of the house, this could also be contributing to the problem but mainly it would be good to do this to eliminate Wifi as the cause entirely. I 100% agree with trying little snitch. Try it denying all connections and see whether you have the problem. Excel for mac shortcut keys. From there you can progressively permit connections and monitor the change in speed as that happens. I would also probably try CCCing the disk and then wiping it, or at the very least booting of a USB into another instance of macOS to eliminate any software, configuration or crazy kernel stuff. I'm curious whether the macbook pro gets a good connection or whether it gets the slow connection as well?
