R36 All speed gone
 

Morning all,

Been having very poor WiFi perfermonace this morning, and logging in to my superhub I see that things have changed. Its now running R36 firmware.

I have read through some other posts on the forum and followed some tips to get the speed back to what it was but nothing has worked.

Things I have tried:
powering off the router
Factory reset the router
dissable UPNP
dissable OBSS
worked through the different speed settings on 2.4ghz then on 5ghz

Im at a loss at what to try next, the hardware can clearly perform as it was working great before, but now it struggles.

Previously it would upload at almost 5meg and download about 85meg (testing on newsgroups)

Now the upload tops out at 0.8meg and the download about 8

Anyone know any other thigs i could try, or is it possible to rollback the firmware?

Thanks for reading
Rumple

Check the wireless channel in use - it may well have changed, especially if on auto. Others have reported the auto function does not work too well in any version of firmware and have had to do their own local survey of channel use and set the channel manually.

One interesting tale I have to tell related to this is that I was called to a friends house after they had a Superhub installed by a VM engineer. Their Wifi performance was poor. The engineer claimed to have set it up optimally.

What I found is that he had simply moved the ethernet cable from old cable modem to the new and left the original Netgear (VM supplied) Wifi router in circuit and powered on. Both Wifi's were still on and the auto-channel function of the Superhub did not know what to do, especially as they had another business Wifi network in the house too. I pulled the Netgear router out of the network, switched to manual channel selection, after checking which channels were in use locally, and everything worked fine.

Thanks for the info.
Currently I have no other wireless devices in use in the house.

Having gone through the channels there was very little difference in speed between them. Some of the 2.4ghz channels were even slower and all the 5ghz performed the same.

Re: R36 All speed gone
 

Have you tried it with an Ethernet cable, if speeds are ok when you use a cable then it confirms a 'wireless' issue.

Re: R36 All speed gone
 

Good idea :)
testing with a wired connection gives 4.8meg upload and 93meg download

So it does seem the WAN can provide the speeds but the wifi is causing a bottleneck.

Re: R36 All speed gone
 

The only thing that seems to sort out the problems with wifi is to put the shub into modem mode and use/buy your own router, which is what I have done. R36 may improved latency , but wifi range and speed it has not improved imo.

Re: R36 All speed gone
 

Rumple, I'm guessing you are using WiFi mode 300Mb/s. Try the 144Mb/s instead.

It's worth getting a copy of inSSIDer so you can actually locate some free WiFi bandwidth.

Re: R36 All speed gone
 

Either your superhub is faulty or your computer's wireless drivers are faulty.

Re: R36 All speed gone
 

I noticed the same, latency has got alot better but my speeds have really dropped. I would hate to buy another router when the hub was working so well before. But if I do is there any that are recommended?

As mentioned in my original post I worked through the 3 speed tiers with no increase in performance. The 54 was actually slower

Thanks for the info about inSSIDer, seems to have a similar purpose to netstumbler?

Been chatting with my neighbour this morning who has allowed me to access his wifi for testing and I get very good speeds. I think this rules out the WiFi performance on my PC side having degraded.

The problem is my WiFI setup has been working very well since it was installed months ago, newsgroup speeds would consistantly be over 80meg. But since the R36 upgrade the speeds have dropped to 10% of that.

Do you think the R36 have caused a fault with the hub?

The driver on my PC wifi is unchanged and as mentioned above my WiFi gets great speeds when connected to other access points.

Its a shame that its not possible to rollback the hub firmware to determin if its a hardware fault that has developed around the time of the firmware upgrade or if the firmware has indeed degraded the wifi performance.

Re: R36 All speed gone
 

Sorry, missed that. I think you have tried most things.

Do you have any possibility to check the speed of file transfer between machines on your own LAN? i.e. between a WiFi connected laptop and some other wired device. That would help rule out (or in) firewall problems.

You can get an idea of this with the ping command but adjusting the data size sent. e.g. on windows...

ping 192.168.0.1 -l 50000

If you divide the data size by half the response time (the ping uses the send and receive path) this should give an appoximate instantaneous rate (in Bytes / second)

Re: R36 All speed gone
 

If you have not done it check if there are updates to the Wifi drivers for your PC. One of the changes VM did was to update the Broadcom driver in the Suberhub. As Broadcom are one of the biggest players out there it is possible, if there are incompatability issues with some Wifi devices, the manufacturers of those devices would move to fix any problem quickly.

One other thing you might try if your factory reset was not done in this exact way (copied for the VM customer forum) is to follow this:

One quick note some users have reported temporary Wireless or Firewall issues after they were first upgraded, but these were solved by logging into the admin menu and doing a full factory reset by clicking on Advanced Settings> Device Management> Reboot Device/Reset Device> Restore to Factory Defaults.

Re: R36 All speed gone
 

Although in theory it should be possible to rollback foreskin :erm:, in this instance I dont think it's possible.

Did you say you had tried a hard reset of the Superhub

Re: R36 All speed gone
 

Update,

I called the virgin chaps on 150 and explained my problem to them. After a min of flashing lights from the hub its now good as it was before.... magic

Thanks for the suggestions though

Re: R36 All speed gone
 

I wonder what they did...

Re: R36 All speed gone
 

Rumple, are you still on R36 or back on R30?
