NVG510 UpStream Issue

Recently, due to AT&T upgrade, my old equipment, (Motorola modem & E1000 router) began to underperform.

My connection is 18Mbps. I was getting 16 down and .8-.9 up. After the change I was getting 8-10 down and .8-.9 up. So actually, only my downstream was affected. AT&T sent out a technician (very polite, very professional) and changed my equipment for free. He gave me the NVG510. Everything fine with downstream. I am back to 16Mbps.

 

The problem is the upstream. Now I am only getting .2 - .3 Mbps. This is true whether I am wired or wireless.

Has anybody had this issue? Any solutions for this issue?

Thank you in advance for any and all answers.

 

Ted.

Re: NVG510 UpStream Issue

If you access the RG (192.168.1.254) and post screen shots.
Looking for max sync rates and SN margins up and down.

Are you testing hardwired from 510 not the E1000.?

Re: NVG510 UpStream Issue

I am not using the E1000 anymore. My hardwired test was with the 510. As an added note, if I go back to my old modem and the E1000, my upstream goes back to .9 but then my downstream goes down to 8 - 10.

Re: NVG510 UpStream Issue

I tried the solution given by DONLUZ, using my E1000 as my router instead of the NVG510, and my upstream has gone back to .9

Re: NVG510 UpStream Issue

While your SN and sync rates look good, your errors do not.
FEC are corrected errors, ideal less than 100 per minute.
CRC are non corrected, when a packet is sent has a check digit like a bar code, a comparison is made between code sent and code received, when not same error. Due to the large number of errors on upload this forces many requests to keep sending the same information. Result, longer it takes to complete the requests the slower the speed. As this is reverse on previous equipment, believe possible inside wiring issue. Did tech leave his contact number, if so request a revisit, tech needs manager approval to come back (gps, and exemption time from job load). If tech did not leave his number need to call or chat for another visit. Sync needs to be checked at NID, and RG. If NID is good RG bad, inside wiring. If sync has issue at NID outside issue

Why does this matter, if no wire protection plan, will be charged to fix inside inside wiring. Normal $99, as original tech did not charge $100 for RG (should have as this is a purchased unit) your be about same as if tech had fixed issue and left you with your original setup.

Just my thoughts....

Re: NVG510 UpStream Issue

As an FYI, the technician also corrected my wiring and installed a new phone jack, and gave me a new filter, even though my old one was probably good. As you can see from my previous post, using my E1000 as my router solved my upstream issue. I will keep tabs on the errors though.

 

Thank you for your time regarding this issue.
